You seem very intelligent, so I want to ask you a bunch of questions I've been saving up when studying circuitry. It's a bombardment of questions, though, so you don't need to answer if you don't have the time. I'm taking physics in school so these questions will help me. -why do you not short circuit a battery by touching both ends with your finers? is skin's resistance so high that it essentially breaks the circuit? -what causes death? Voltage or current? -how can birds sit on power lines? -if a capacitor is 10 microfarads, in an RC circuit, then at t=c, where c is a random constant, the capacitor can hold the maximum charge of a 5 microfarad capacitor, maybe later the max charge for a 6 microfarad capacitor, maybe earlier the maximum charge of a 3 microfarad capacitor? -why does a circuit complete itself if you are standing on the ground and you touch a charged conductor that's connected to a battery or transformer on the ground? -is a battery connected to ground if its physically touching the ground or does it need to connect itself to a long metal pipe in the ground? -does voltage come out of the negative or positive side of a battery? -why does emf exist? Why is it important in circuitry?
@coreylevinson73399 жыл бұрын
-how does a capacitor charge if it's not a circuit? -why must a circuit connect back onto itself? I understand its necessary to have a complete circuit oelectrons can flow, but why? -if you have high voltage in a wire, why doesnt a spark form in between a switch? -if a high capacitance capacitor is fully charged, why doesn't a spark form in between? -Why are wires covered in conductors? -what's so good about coaxial cables? -if a resistor has a really high resistance, is it possible to effectively cut off the current, thus breaking the circuit? -is a lightbulb flickering really quickly? I think the answer is no but I dont know. -imagine two circuits each with a battery with potential V. In both circuits there is one resistor. In the fist circuit, the resistor is 1 ohm. In the second circuit, the resistor is 10000 ohms. Which circuit depletes the battery faster? -what happens if a battery is fully charged and you try to charge it even more (i understand this question might have more to do with chemistry than physics) -How does grounding work? Why is it important? -what is bemf?

Here's why I like this video so much. We all get these textbooks in school that show us examples, and our professors try to teach us this subject and another five or more concepts in a 1 hour lecture if that. When you can get a singled out explanation for something like this, it's soo much easier to sink in and understand. Thanks. I have a request though; can you make a video about the Voltages of the Capacitor in an RC circuit and how it changes through 5 time constants?

Hi There, At time-stamp 1:43 Your last statement is: Two things - capacitors are charged and current is running through those two capacitors... Most likely you wanted to say: capacitors are charged and current is running through those two RESISTORS... ;-) Your tutorials are great!!! I LOVE them... I am going over them and taking notes... I have become so good I even started catching the MASTER's miss-spells... ;-) I am sure you meant Resistors... Like in the prior video you said 25 amps instead of 20 amps...

@wronski118 жыл бұрын
What would happen if your 10 Ohm resistor was a capacitor. If there was no 20 Ohm resistor, you are just going to charge the capacitors. If the 20 Ohms are there however, would you be charging the capacitors with less current? Under normal circumstances, if the 10 Ohm was replaced with a capacitor, they would be in series and all capacitors will have the same charge. However, I am not sure what will happen if the 20 Ohm is connected in parallel to the 12 uF and the 6 uF. Would it be preventing them to get the same charge as the capacitor which we used to replace the 10 Ohm resistor?

My argument here is that, based on my past experiences with circuit analysis, both resistors are not in series (nor parallel). I have been taught that, when there are circuit elements connected between two resistors, they fundamentally cannot be called in series (reference node X and the elements, the 2 capacitors, below it). Since the assumption here states that, in this case, the capacitors are fully charged, would this be an exception? With both capacitors fully charged on the middle wire, can we then say that the 2 resistors are in fact in series? Also, what if the capacitor(s) where not charge, could we still say that the resistors are in series?

We don't really say the total charge "over" the two caps....it is really about the charge stored on the capacitors or the potential difference across the capacitors. If their capacitances are different, then the charge and the potential differences will also be different.
