I think someone already posted the link but this video might answer your questions:

The total stored energy is half the potencial energy because you lose voltage while discharging the...
Imagine you have 2 pendulums (they are exactly alike, same period) that you use to measure time, then you take the pendulum #2 and move it at certain speed relative to the pendulum #1. If you record the total amount of distance that the ball on pendulum #2 traveled over a period we willl see...
I think you're getting confused because you are trying to compare the voltage (electric potencial) with the energy of a mass at certain height (potencial energy). They are not the same thing (the units are not the same). Imagine you have a mass at a certain height the Potencial energy would be...
I read the following problem on a textbook:
A airplane flies at a constant speed of 680m/s perpendiculary to Earth's magnetic field (of 5x10^-5 T). The wingspan of the airplane is 9.8m. What is the induced voltage?
The answer the book gives is: E = BLv = 0.4066V
But I've been wondering if this...
