The scale of an ammeter is shown below : The least count of this ammeter is :
The reading of the ideal ammeter will be (Resistance of ideal ammeters is zero)
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.
An ammeter gives full deflection when a current of 2 amp . Flows through it. The resistance of ammeter is 12 ohms . If the same ammeter is to be used for measuring a maximum current of 5 amp , then the ammeter must be connected with a resistance of
The resistance of ammeter is R_(0)
In Fig. 6.61 the voltmetre and ammeter shows are ideal. Then voltmeter and ammeter readings, respectively, are
Reading of ammeter is
