In the adjacent circuit the ammeter reads 5.0 A and voltmeter reads 20V. The value of resistance R is

In the circuit shown below, the ammeter A reads 5 A and the voltmeter V reads 20 V The correct value of resistance R is

In the circuit shown in Fig. 4.25, the voltmeter reads 1.5 V, when the key is open. When the key is closed, the voltmeter reads 1.35 V and ammeter reads 1.5 A. Find the emf and the internal resistance of the cell.

In the circuit shown, A and V are ideal ammeter and voltmeter respectively. Reading of the voltmeter will be

In the circuit shown, A and V are ideal ammeter and voltmeter respectively. Reading of the voltmeter will be

In the circuit shown, A and V are ideal ammeter and voltmeter respectively. Reading of the voltmeter will be

When key K is open in a circuit as shown in figure, an ideal voltmeter reads 1.53 V. If key is closed then ideal ammeter reads 1A and voltmeter reads 1.03 V. Then EMF of cell and external resistance R are respectively

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
