The charge of the capacitor, the current in the circuit, and, correspondingly, the voltages across the resistor and the capacitor will be changing. Note that at any moment in time during the life of our circuit, Kirchhoff's loop rule holds and, indeed, it is helpful: E−VR−VC=0, where VR is the voltage across the resistor and VC is the voltage across the capacitor. A) In the steady-state, what is the charge q of the capacitor? B) How much work W is done by the voltage source by the time the steady state is reached?
