But what if I see the voltage as the amount of potential energy the electron loses as it moves towards the positive terminal of the battery? Why does it lose this energy in the first example but not in the second?

Hello again! Sorry to be a pain, but I'm still having trouble understanding. I understand now, thanks to your answers, how voltage changes throughout the circuit, but I don't understand why the following sentence is true: "Two points in an electric circuit that are connected by an ideal...

I think what's confusing me is the fact that I read that electric potential is a location-dependent quantity. So, for example, a positive test charge near a positively charged source will move away from the source, losing electric potential energy and gaining kinetic energy. I don't understand...

So if there were no lamp, would each charge have 5V of electric potential even when it reached the low-potential end of the circuit?

Hi, thanks for your replies. If the charge doesn't lose electric potential, why is it at 0V when it reaches the low potential terminal? Does a charge not lose electric potential as it moves through an electric field?

Hi, I'm just starting to study circuits, and there's a thing I don't understand about electric potential. I was under the impression that as a charge moves through the circuit from the high potential end of the battery to the low potential end, it lost electric potential energy which...

Hi, thanks for your replies! So am I right in saying that when the wave reaches a point at rest, the point starts to move with a harmonic motion in which its point of rest becomes the middle point of the motion (i.e. where its speed is greatest)? How can we show that the equation describes...

Hi, I have recently been studying waves, and I understand the transversal wave formula y=Asin(w(t-x/v)) which gives the y coordinate of a point at x along the x-axis in the instant t. However, Wikipedia (http://en.wikipedia.org/wiki/Longitudinal_wave) gives this as the equation for...
