A 3.9 MΩ and a 2.2 μF capacitor are connected in series with an ideal battery with an EMF of 3 V. At 3 seconds after the circuit is initially connected to the battery:
a) What is the rate at which the charge on the capacitor is increasing?
dq/dt = C/sec
b) What is the rate at which energy is being stored on the capacitor?
dU/dt = J/sec
c) What is the rate at which thermal energy is appearing in the resistor?
dEthermal/dt = J/sec
d) What is the rate a which energy is being delivered by the battery?
dEBattery/dt = J/sec
