The battery is charged from full wave rectifier fed by a sinusoidal voltage see figure Ideal diodes ammeter and voltmeter show the time average value At idle with only key K closed voltmeter shows 12 V and current is then absent ie reading of ammeter is 0 If only the key K is closed the voltmeter shows battery voltage at 12 3 V During charging when the K and K are closed the voltmeter shows 12 8 V and ammeter shows 5 A Find the internal resistance of battery K A K P V
