Question

A galvanometer of 50 $\Omega$ resistance has 25 division. A current of $4×10^{-4} A$ gives a deflection of one division. To convert this galvanometer into a voltmeter having a range of 25 V, it should be connected with a resistance of:

• A. $2500 \Omega$ as shunt
• B. $245 \Omega$ as shunt
• C. $2550 \Omega$ as shunt
• D. $2450 \Omega$ as shunt

Answer 1

Answer: (D)

$2450 \Omega$ as shunt

Answer 2

The correct option is(D):$2450 \Omega$ as shunt
