<<@TheOrganicChemistryTutor says : Series and Parallel Circuits: https://www.youtube.com/watch?v=wejz5s31Cts Video Lessons by Chapter: https://www.video-tutor.net/>> <<@itsmr.gengar3937 says : Bro was so goated and overpowered, He had to nerf himself. He went from teaching complex STEM topics to teaching basic math concepts.>> <<@sajjad-n1h says : I believe the speed of the electromagnetic wave (in this case, electricity) depends on the medium it travels through — which is the wire (probably copper) — and nothing else. Therefore, there are more electrons, and the speed (or propagation time) remains the same in both cases.>> <<@AbiruddinAbir.victorVon says : god bless this guy>> <<@loudhills2 says : lowky funny how bro went from completing nearly all hard topics and is now doing kids content>> <<@TheAnimeKid778 says : love how this video was next to a video on subtracting fractions and another as an intro to fractions>> <<@charitythompson2205 says : bro if it werent for this guy idk where i would be>> <<@toplistvideos6407 says : This man is a legend. He single handedly helped me, and thousands of others, pass high school and college>> <<@bbaaddgamers199 says : The relationship between electric current and resistance is a bit complicated. Resistance affects electric current, but current does not affect resistance, but rather the potential difference. If the resistance is constant and we increase the electric current, this means that we will double the speed of electron flow in the wire, as shown in the video. Thus, the voltage required to move these electrons at the new speed will increase (i.e., the electrons will not decrease if we increase the electric current because the effect is not reciprocal in the inverse relationship between electric current and resistance. Thus, I am almost certain that time will not change, but the speed of the charges will only increase).>> <<@lemonexperiments says : umm i see u have covered almost every topic and now u have reached to a point of remaking video and posting like clss 3 stuff, idk if it is a good thing like an achievement or a bad think as your views are decreasing but like thanks man for everything you have taught me!>> <<@simarveersingh7390 says : Congratulations on 10 Million subscribers🥳🥳🥳>> <<@TheWind1337 says : plscomeback>> <<@CREEPEEERR says : bro please make a video on deuterium exchange😭😭>> <<@danalex5206 says : Can you make a AP statistics course>> <<@JosephGonzalesJo says : Happy Teachers' Day!>> <<@losja.d2005 says : It’s the same>> <<@YomaGodspower-AKpomiemie says : I have a question : how does movement cause electricity please be kind, it's a genuine question, I am very new at this circuit stuff>> <<@Black-e7u1l says : Everyone is going to graduate for you thanks Algebra 1 , 2 Geometry pre calculus and now electrical.

So, for the 24V, i say it's the same electrons with double the speed. As for the resistance, i think that the lesser the resistance, the more electrons can pass through. So, for the 1.5 ohm, i say it's double the electrons with the same speed. I'm just speculating here. I'm not quite knowledgeable in physics. So, don't come after me.>> <<@Joeyknapp43 says : in these batteries the current is increasing not because there are more electrons but because in the second battery the potential voltage increased and the resistance stayed the same. In the third battery the potential voltage stayed the same but the resistance dropped. Current and resistance are inversely related. So with the resistance dropping, the current will increase.>> <<@1sham.elyasmin says : ❤>> <<@UPT12-y7w says : Thank you>> <<@IrtizaSariyanFerdousi says : U SAVED MY LIFE. ACTUALLY U R SAVING MY LIFE EVERY FUCKING YEAR U SAVE MY LIFEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE. LOVE U SO MUCH!!! TYSMMMMMMMM>> <<@zach1232j says : Hi, could you cover Stokes law or Greens law if possible?>> <<@ovzibq says : We needa face reveal>> <<@brilliantbreak says : I would love if you start teaching Vastu>> <<@RealMrFN says : ❤>> <<@jamesashons9227 says : Hello sir, I was curious if its ok if I download your videos for offline use?>> <<@kimberlyalfaro9904 says : QUESTION: Can you even duplicate/double electrons??? 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.

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>>
