CUMULATIVE PROBLEM A 12.5-μF capacitor is charged to a potential of 30.0 V and then discharged through a 65.0-Ω resistor. 1) How long after discharge begins does it take for the capacitor to lose 90.0% of its initial charge? 2) How long after discharge begins does it take for the capacitor to lose 90.0% of its initial energy? 3) What is the current through the resistor at the time when the capacitor has lost 90.0% of its initial charge? 4) What is the current through the resistor at the time when the capacitor has lost 90.0% of its initial energy?

          **CUMULATIVE PROBLEM**
A 12.5-μF capacitor is charged to a potential of 30.0 V and then discharged through a 65.0-Ω resistor.
1) How long after discharge begins does it take for the capacitor to lose 90.0% of its initial charge?
2) How long after discharge begins does it take for the capacitor to lose 90.0% of its initial energy?
3) What is the current through the resistor at the time when the capacitor has lost 90.0% of its initial charge?
4) What is the current through the resistor at the time when the capacitor has lost 90.0% of its initial energy?
