Question

A moving coil galvanometer of coil resistance 12 ohms shows full scale deflection for a current of 3 mA. It can be converted into a voltmeter of range 0-18 V by connecting

• A. 0.01 ohms in series with the galvanometer
• B. 5988 ohms in parallel with the galvanometer
• C. 0.01 ohms in parallel with the galvanometer
• D. 5988 ohms in series with the galvanometer
• E. 6200 ohms in series with the galvanometer

Hint:

V for Voltmeter \(\rightarrow\) S for Series (High R).
A for Ammeter \(\rightarrow\) P for Parallel (Low R).
This mnemonic helps you remember the correct configuration for conversion.

Answer 1

The Correct Option is D
