No. If it is unchanging, then no electrical energy will be...
OH. It makes this question so much easier now, thanks. bundles.
I've come to determine my upper plate is negative cause the electrons flow into it.
again, thanks so much.
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...
