Question

A moving coil galvanometer, having a resistance G, produces full scale deflection when a current Ig flows through it. This galvanometer can be converted into (i) an ammeter of range 0 to I₀(I₀ > I g) by connecting a shunt resistance R A to it and (ii) into a voltmeter of range 0 to V (V = GI₀) by connecting a series resistance R V to it. Then,

Accepted Answer

(D) R A R V = G² and R A /R V = (I g /(I₀ - I g))²

Answer

(A) R A R V = G² and R A /R V = I g /((I₀ - I g))

Answer

(B) R A R V = G²(I g /(I₀ - I g)) and R A /R V = ((I₀ - I g)/I g)²

Answer

(C) R A R V = G²((I₀ - I g)/I g) and R A /R V = (I g /(I₀ - I g))²
