A 1.02 μF capacitor that is initially uncharged is connected in series with a 8.00 kΩ resistor and an emf source with 77.2 V and negligible internal resistance. The circuit is completed at t = 0.

Part A

Just after the circuit is completed, what is the rate at which electrical energy is being dissipated in the resistor?

Express your answer with the appropriate units.

Part B

At what value of tt 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?

Express your answer with the appropriate units.

Part C

At the time calculated in part B, what is the rate at which electrical energy is being dissipated in the resistor?

Express your answer with the appropriate units.

Answer #1

Note that time at which rate of energy dissipation by resistor is equal to the rate at which energy is stored in capacitor is t = 0.

Thus, rate at which energy is dissipated by resistor at t = 0 is same as in part A, hence, 0.745 W
