A 1.0 mF capacitor with an initial stored energy of 0.50 J is discharged through a 1.0 M resistor. (a) What is the initial charge on the capacitor? (b) What is the current through the resistor when the discharge starts? Find an expression that gives, as a function of time t, (c) the potential difference VC across the capacitor, (d) the potential difference VR across the resistor, and (e) the rate at which thermal energy is produced in the resistor.
