A 14.5-μμF capacitor is charged to a potential of 40.0 V and then discharged through a 65.0 ΩΩ resistor. 1)How long after discharge begins does it take for the capacitor to lose 90.0% of its initial charge? (Express your answer to three significant figures.) 2)How long after discharge begins does it take for the capacitor to lose 90.0% of its initial energy? (Express your answer to three significant figures.) 3)What is the current through the resistor at the time when the capacitor has lost 90.0% of its initial charge? (Express your answer to three significant figures.)
