Distinguish between ammeter and voltmeter.

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

If the resistance R_(1) is increased how will the reading of the ammeter and voltmeter change

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.

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

A students connects an ammeter A and a voltmeter V to measure a resistancer as shown in figure. If the voltmeter reads 20 V and the ammeter reads 4A , then R is

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

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
