Chapter 26, Problem 26.71P
A 2.00-µF capacitor that is initially uncharged is connected in series with a 6.00-kΩ resistor and an emf source with ε = 90.0 V and negligible internal resistance. The circuit is completed at t = 0. (a) Just after the circuit is completed, what is the rate at which electrical energy is being dissipated in the resistor? (b) At what value of t is the rate at which electrical energy is being dissipated in the resistor equal to the rate at which electrical energy is being stored in the capacitor? (c) At the time calculated in part (b), what is the rate at which electrical energy is being dissipated in the resistor?
