Q1:

Two meters X and Y require 40 mA and 50 mA for full scale deflection. Then

A X is more sensitive

B Y is more sensitive

C both are equally sensitive

D it is not possible to determine from given data

ANS:D - it is not possible to determine from given data

Sensitivity is inversely proportional to current (i.e Ifsd).

Here data is sufficient to find the sensitivity of this two meters.

X is more sensitive than Y.
