A circuit contains a resistor and an uncharged capacitor. Pointing into the plane of the circuit is a uniform magnetic field (B). If the magnetic field increases in magnitude with time, which plate of the capacitor (top or bottom) becomes positively charged?
I don't understand how the hand rules play into this question, because of the capacitor. And I don't understand how I'm supposed to figure out which plate is positive and which is negative. Please help me out?
Thanks in advance, guys. :shy:
