Conversation of Galvanometer as Ammeter

Conversion of Galvanometer

A galvanometer has a current range of 15mA and voltage range of 750mv. To convert this galvanometer into an ammeter of range 25A, the sunt resistance required is nearly

The device used for producing electric current is called a: (a) generator. (b) galvanometer. (c) ammeter. (d) motor.

A galvanometer having a coil resistance of 100 omega gives a full scale deflection , when a current of 1 mA is passed through it. The value of the resistance, which can convert this galvanometer into ammeter giving a full scale deflection for a current of 10A , is :

To convert galvanometer into ammeter which one of the following is connected with the coil:

A galvanometer has resistance G and full scale deflection current i. To convert this galvanometer into an ammeter of range 10 I, a shunt S = (G)/(9) is connected in parallel with G. Now we want to measure potential difference with the help of this ammeter. What is the maximum value of potential difference which can be measured with the help of this?

In tangent galvanometer generally for more accuracy deflection of galvanometer should be taken in range of

Distinguish between Galvanometer and ammeter

The conversion of a moving coil galvanometer into a voltmeter is done by
