2) A 400 [I resistor and a 50 pl\" capacitor are hooked up in series to a 3.0 V battery. Before they are all connected, there is no charge on the capacitor. a) What is the current in this circuit as a function of time? b) How much power does the resistor use as a function of time? c) How much energy is stored in the capacitor as a function of time? d} After a very long time (so the capacitor is essentially fully charged to its limiting value}, the components are disconnected and the capacitor discharged through a 250 k resistor. [That is, it is just hooked up to this resistor in a simple loop.) How long does it take for 99% of the energy to be drained from the capacitor
