In the circuit shown in Fig. , e.m.f. batteries of elements E = 10 V, all external resistances are the same and equal to R = 5 Ohms each, the capacitances of all capacitors are also the same and equal to C = 900 cm each. Find the charges on the capacitor plates if, when the battery is short-circuited, the current through it increases by n = 9 times.
