Question 324: Current Electricity

Question

A galvanometer is used in laboratory for
detecting the null point in electrical
experiments. If, on passing a current of 6 mA it
produces a deflection of 2
o
, its figure of merit
is close to :

Accepted Answer

figure of merit = $${I \over 	heta }$$
= $${{6 	imes {{10}^{ - 3}}} \over 2}$$
