Question

A voltmeter is given to you to measure the voltage. Which voltmeter will you choose?

hintHint:

Pointer at zero mark means an error free reading.

The correct answer is:


    • The pointer of the voltmeter is exactly at zero, when the circuit is not connected.
    • This means the instrument has no zero error.
    • If the pointer is above or below the zero mark, means the instrument has an error.
    • Therefore, the voltmeter given in option d is to be chosen for accurate reading.
    • So, the correct option is d.
