Question

A galvanometer of \( 50\Omega \) resistance is converted into an ammeter using a shunt resistance of \( 10\Omega \). If the same resistance is used to convert the same galvanometer into a voltmeter, what would be the ratio of the resistance of the ammeter to the resistance of the voltmeter?

• A. \( 5 : 1 \)
• B. \( 5 : 36 \)
• C. \( 5 : 6 \)
• D. \( 1 : 5 \)

Hint:

Ammeter uses parallel (low resistance), voltmeter uses series (high resistance). Always apply correct combination formulas.

Answer 1

The Correct Option is B
