Psssst...what is the answer? ( I don't like Physics 🙁)>> <<@kimberlyalfaro9904 says : I think is the same number of electrons twice the speed. I might be wrong. I think of an atom for example (When something is heated, the electrons' speed and kinetic energy increase, leading to faster atomic vibrations and more collisions. The number of electrons in a material generally does not change, but some electrons might jump to higher energy levels (like the conduction band in semiconductors) due to the increased thermal energy: Google))>> <<@paulinenegoli677 says : Omz??????????????????????>> <<@am4ryll1s says : my goat>> <<@KavPatelXCSRV says : Could you start anatomy lessons pls? Btw, ty for carrying me!>> <<@ColinUmeyama says : HERE IS MY EXPLANATION: WHY IT IS -(the doubled amount of electrons travelling at the same speed)-: In an electrical circuit, current (amps) refers to the flow rate of electrons—how many pass through a given point in one second. When voltage doubles (while resistance stays the same), the number of electrons flowing per second increases, but their individual speed doesn’t change significantly. Think of it like more water flowing through a pipe when you increase pressure—the amount of water molecules passing a point per second goes up, but the molecules themselves aren’t moving twice as fast. WHY IT ISN'T -( the doubled amp means same amount of electrons but 2x the speed)-: Because in a typical circuit, electron speed (drift velocity) is extremely slow—often just millimetres per second. When you double the voltage, what actually happens is that more electrons flow per second, not that each electron suddenly moves twice as fast. The increase in current is due to a higher rate of charge flow (more electrons passing through per second), rather than individual electrons accelerating significantly. If voltage increases, the electric field pushing the electrons gets stronger, but that mainly affects how many electrons move—not their speed in a simple circuit like this. The speed change would be negligible, making option B (more electrons at the same speed) the most accurate.because in a typical circuit, electron speed (drift velocity) is extremely slow—often just millimeters per second.

The speed change would be negligible, making option B (more electrons at the same speed) the most accurate. WHY IT ISN'T -(a bit of both)-: In a simple DC circuit like this, voltage affects the amount of charge carriers moving (the number of electrons per second), not their speed. Electron speed, or drift velocity, is actually very slow in a circuit—much slower than you’d expect, often millimeters per second! What makes electricity appear instant is the electric field propagating through the wire, causing electrons to begin moving throughout the circuit almost immediately. Since current (amps) = charge flow per second, when we doubled the voltage while keeping resistance the same, it resulted in twice the amount of electrons moving per second, not electrons moving twice as fast. I hope this helps all of you!>> <<@ColinUmeyama says : In an electrical circuit, current (amps) refers to the flow rate of electrons—how many pass through a given point in one second.

Hope that makes sense!>> <<@RyanDouglas-h3d says : Both is my answer. I think of the pathway the electrons flow like a highway for cars: increasing the voltage is like widening the highway - safely allowing _more_ cars to move with _higher_ speed. Narrow the highway (lowering the voltage) means less cars can safely travel through at speed and have to travel slower.>> <<@yviiv says : hi ive been watching your videos for a while and theyve really helped me wirh my studies from year9 through to 11. im in year 11 now, and im trying to make video tutorials for myself on chemistry, maths and physics that cover my schools syllabus, and i was just wondering platform you use to record your voice and make these videos. I was going to comment on a more recent video but the commenta had been disabled 😅>> <<@TrackerMKS-b6d says : Can you please upload more calculus 3 vids about green’s theorem and stokes theorem and more of vector fields and line integrals and also a lot more of Multivariable calculus?>> <<@darinprimal487 says : rename your channel to Tutor of All Trades.>> <<@misskyleigh2999 says : I'm thinking when you increase voltage, the current grows because of an increase in number of electrons, but when you decrease resistance it grows because of an increase in the current number of electrons' speed.>> <<@marcomikemarco says : Hi, good question. I've been there too. in general the answer is "both". meaning that the application of a higher voltage will cause the emission of more electrons and higher voltage means higher electric field within the material and this will cause higher acceleration of electrons between collisions, thus an higher average velocity. in the case of conductors i'd say that the availability of free electrons is much higher than the need for conduction, so the second mechanism applies. with higher voltage you have higher electric field within the material, so higher average velocity, and so higher current. when you move towards high resistance values and conductors are not "ohmic" anymore you need to spend voltage to generate high energy electrons that can be promoted to conduction, so this might be the limiting factor then. but your question is about the Ohm's law, right?>> <<@ganeshgump5034 says : will you be doing any videos on special relativity for physics 2?>> <<@dhc21atyahoo says : Depends on the length, surface area and the nature of the conductor attached to said resistance. So given the same type of resistor, it would depend on the wire gauge, type of metal and wire length.>> <<@victini6266 says : I can’t believe you’re still posting videos on these subjects. You’re so many people’s hero man, thank you for your guidance 🙏✨>> <<@Frpv1 says : Résistance classique : R=Rho x L / A Résistance géométrique : R=Rho x L _ équivalent / A>> <<@grandgraph says : Literally just learnt this yesterday u came in clutch>> <<@nirmalmishra6404 says : Drift velocity=i/ena, when V gets twice so gets the current and so gets the Drift velocity>> <<@vinitagain5802 says : 1:51 Double electrons in same speed>> <<@rafatali1170 says : Sir, you have to upload the solution of this problem even we get the answer in the comment section. Your algorithmic concept is unique to solve any problem.>> <<@esrx7a says : V is directly proportional to I, increase in Voltage will increase the Current, constant being Resistance. More Voltage is speeding up the flow of Current across the circuit. Hence requiring the need for resistors as current limiting elements. (I may be wrong, open for corrections)>> <<@BappiDebnath-qo3hn says : Bro you said on a video that a charge plate which has zero potential but it was negatively charge. How it is possible how a charge plate is negativity charge with zero potential 😢. Title of this video was electric potential.>> <<@SalmanSunny-mk6tv says : nice😊>> <<@ovfbekw5467 says : Idk man that’s a good question>> <<@tonidaluv2224 says : is the final answer is double electrons? cuz same voltage in two cases but the current is double.>> <<@sagd636 says : talking from thinking here no evidence to back me up 1.so i believe when u increase the voltage the attraction of the poles/terminals is much stronger causing electrons to come faster(increased speed) to "+" terminal. I don't think the number of electrons increases with voltage because the overall charge or net charge of the wire has to be the same conc: speed increases when voltage increases 2. when u decrease the resistance less electrons are slowed down, the slowed down electrons still go to "+" side they regain their speed from the attractive force of positive , I imagine the litteraly hit the atoms/ions of the resistor and get slowed down ,so only the ones who haven't got attracted/hitted another atom would cross while mantaining the net charge now lets think -have to maintain same overall net charge -some getting discarded from the pack -less went through then enterd(only when first current started) so with this i can only think of one thing it has to be speed because they can't gain more charge per electron so the speed of electron passing by should match the electron deficit conc: speed increases when resistance decreases>> <<@ninjanimarkus6077 says : 2 days before my physics test is crazyyy>> <<@DoomsdayDoctor says : Just Subscribed 😊😊>> <<@SthabisoNgubane-wk3rc says : The best teacher,can you please do Laplace transform lessons.>> <<@ShandaP018 says : Can you cover quality factor, phasors, poynting vectors, and apparent depth ?>> <<@crispy1 says : Both cases increasing amps is 😅ncreasing electrons when raising voltage and also when reducing resistance slows movement of increased electrons>> <<@MadCommenterOG says : Thanks so much for this, I have my physics exam in 1 hour. It is my finals to pass the grade.>> <<@Q-Productions23 says : Thank you so much!! I've got my physics exams in a month. Much needed>> <<@xxmorlyxx4163 says : You always been a savior for my science subjects in uni thanks sm for all the videos 🙏🏼>> <<@Gencgello says : The speed of the electrons are always the same. Thus, speed of light (theoretically without a resistance) Since the resistance are the same, the speed on both scenarios will be the same. Since the equation is linear, an double of increase of voltage will double the amount of electrons. However, the speed will be the same, slightly below speed of light, due to the resistance being the same.>> <<@MadinaKaratayeva-l8o says : Hiii dear tutor! Thank you very much for your lessons!! They’re literally saving my life!!! I have a question about your paid membership in YouTube and Patreon, which one is better or are the content of both is the same?>> <<@DazzlingSunshine-o7j says : i do believe it depends on conductivity of the wire.>> <<@ClownManTom says : LETS GOOOOO>> <<@私は鳥じゃありません私は豚だ says : I think by reducing the resistance we get electrons flowing faster through system. Instead of making them go through one by one, we increase the area(R=L/A) so we get more electrons passing from one point. Thus we have same number of electrons flowing at twice the speed>> <<@maggie12md18 says : Oh boy this fresh video just dropped one hour ago!>> <<@Razumutaz says : I just wanna than you for providing a simple, quick, and free education to millions. Thank you so much for helping me do well in algebra 2>> <<@GáborDemény-f7w says : That another level of April fools :D>> <<@reeeemaaaaa says : Thanks! Keep going!>>
