In the given figure when the key is open the ammeter reading is 5 amp. What will be the ammeter reading when the key is closed

In the circuit shown in Fig.4.20 both the ammeter and the cell have negligible resistance. Three external resistors are identical. When the switch S is opened, the ammeter reads 0.6 A. What will the ammeter read when the switch S is closed ?

The ammeter reading in the given circuit is

The ammeter reading in the given circuit is

How will the rending of the ammeter change if the key K is closed?

In the circuit shown in Fig. 6.50 , an idel ammeter and an ideal voltmeter are used. Whan the key is open, the voltmeter reads 1.53 V . When the key is closed, the ammeter reads 1.0 A and the voltmeter reads 1.03 V . The resistance R is
