Determine the amount of heat Q liberat-

ed in the resistor starting from this mo-

ment.

3.46. A battery of emf e, two capacitors of

capacitance C^1 and C2, and a resistor of re-

sistance R are connected as shown in

Fig. 104.

Find the amount of heat Q liberated in

the resistor after the key K is switched.

3.47. In the circuit diagram shown in

Fig. 105, the capacitor of capacitance C
