Question

A 3.00-μF capacitor, initially charged to 24 V, discharges when it is connected in series with a resistor.
(a) How much energy does this capacitor store when fully charged?
(b) What is the capacitor’s voltage when it has only half of its maximum energy? Is it 12 V? Why or why not?
(c) What resistance is necessary to cause the capacitor to have only of its energy left after 0.50 s of discharge?
(d) What is the current in the resistor at this time?
