In the diagram shown, the reading of voltmeter is 20 V and that of ammeter is 4 A . The value of R should be (Consider given ammeter and voltmeter are not ideal)

Assertion : In the circuit shown in figure ammeter and voltmeter are non-ideal. Why positions of ammeter and voltmeter are changed, reading of ammeter will increase while of voltmeter will decrease. Reason : Resistance of an ideal ammeter is zero while that of an ideal voltmeter is infinite.

The reading of ammeter and voltmeter in the following circuit are respectively

In the circuit shown here, the readings of the ammeter and voltmeter are
