# 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 > Ig) by connecting a shunt resistance RA to it and (ii) into a voltmeter of range 0 to V(V = GI0) by connecting a series resistance RV to it. Then, a) RARV = G2 and b) RARV = G2 and  c) RARV = G2 and d) RARV = G2  and

## Question ID - 51541 | SaraNextGen Top Answer 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 > Ig) by connecting a shunt resistance RA to it and (ii) into a voltmeter of range 0 to V(V = GI0) by connecting a series resistance RV to it. Then, a) RARV = G2 and b) RARV = G2 and  c) RARV = G2 and d) RARV = G2  and

Answer Key / Explanation : (a) -

V = Ig (RV + G) = GI0             …(1)

(I0 – Ig)RA = IgG                       ...(2)

From (1), RV =

From (2), RA =

⇒ RARV = G2
