In the circuit shown in figure ammeter and voltmeter are ideal. If E=4 V,R=9Omega and r=1Omega then readings of ammeter and voltmeter are

The ammeter A reads 2A and the voltmeter V reads 20V, the value of resistance R is (Assuming finite resistance's of ammeter and voltmeter)

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)

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

For the adjoining circuit diagram, the readings of ammeter and voltmeter are 2A and 120 V respectively. If the value of R is 75 Omega , then the voltmeter resistance will be

In the adjoining circuit diagram, the readings of ammeter and voltmeter are 2 A and 120 V, respectively. If the value of R is 75Omega , then the voltmeter resistance will be
