Question

A galvanometer has a resistance of 20 ohms and gives full scale deflection when a current of
0.001 A flows in it. What will be the value of shunt resistance to convert it into an emmeter of
range 10amperes?
(a) 0.002 ohms (b) 0.009 ohms (c) 1.351 ohms (d) 2.193 ohms (e)3.563 ohms

Answer 1

Answer:

A galvanometer has resistance of 30ohm and a current of 2mA is needed to give a full scale deflection. What is the resistance needed and how is it to be connected to convert the galvanometer:

(a) into an ammeter with a range of 0.3 ampere

(b) into a voltmeter with a range of 0.2 volt
