(a) In the given circuit, when the switch is OFF, the voltmeter reads 9 V and ammeter reads 0 A. However, when the switch is ON, the voltmeter reads 7V and ammeter reads 250 mA. Explain why the volmeter reading decreases when the switch is closed? Calculate the values of load resistance (R) and internal resistance (r). A
