A 20-mH inductor and an 8-µF capacitor are used to build an LC circuit.At t = 0,the circuit has the maximum current of 0.50A. What is the voltage across the capacitor at that time?
A)0 V
B)15 V
C)25 V
D)49 V

At t = 0, when the current in an LC circuit is at its maximum, the capacitor is completely uncharged, meaning the voltage across it is 0 V. This is because the energy in the circuit is entirely stored in the magnetic field of the inductor at this moment.
