Problem 3.205

In a circuit shown in Fig. 3.57 the capacitance of each capacitor is equal to $C$ and the resistance, to $R$. One of the capacitors was connected to a voltage $V_{0}$ and then at the moment $t=0$ was shorted by means of the switch $S w$. Find: (a) a current $I$ in the circuit as a function of time $t$ (b) the amount of generated heat provided a dependence $I(t)$ is known.
