Thank you by the way!

My apologies, I meant volt

In fact, my textbook actually describes the capacitance of a capacitor as being the charge stored per unit pd. Is this the same as the charge needed to cause one unit pd in the circuit?

Would it be wrong to describe Capacitance as being the charge stored per unit volt? I have found on the internet that the definition of a Farad is the charge needed to cause one unit volt. Which means that the definition of Capacitance should surely be the same because the internet definition...

Brilliant. Thanks all!

But how can it be a scalar quantity when it contains a vector quantity?

I was just wondering how the kinetic energy in, for example, a car undergoing circular motion is constant. We know that it's constantly acceleration due to the constant change in velocity, but surely that means that in the KE equation (1/2mv^2) the velocity is constantly changing as well. This...

How, exactly, can this current flow when the circuit is not connected? Throughout all my studies, they've drawn the conclusion that when the circuit breaks, or in this case never was connected, the current immediately stops , or never flows to begin with.

[FONT="Book Antiqua"]As everybody already knows, voltage is defined as the work done/energy per unit charge. I see voltage as being the idea of giving the charge carriers a 'want' to move: when a closed circuit is attached to a battery, the voltage makes the charges want to move, and they can...

I understand, thanks to basic physics concepts, that when the electrons flow through the circuit from the negative terminal to the positive terminal, the conventional flows from the positive terminal to the negative. Am I right in thinking that in firing an electron beam, the conventional...

I'm not planning on building one, no. Perhaps in the future but at the minute, I'll stick to understanding the basic theories and concepts of physics in general. I don't think I'm ready to take the risk!

Brilliant! I'm following the logic now you've explained it so well. Thank you for all the help.

Thank you, first of all, for your speedy response. I'm not actually sure what you mean here. If you passed the A.C current through the step-up transformer, then connected that to the primary coil, the constantly changing direction of the charges means a constantly changing flux due to the...

Hi to all, It may be a low-level question, but nevertheless, one to which I'm looking for an answer. The main question is as follows: - Within a Tesla coil, what is the main purpose of the capacitor and spark gap? Other such questions arising from the principle question: - What would...
