Question

Amount of deflection of the galvanometer depends on _________

(a) resistance of the ratio arms

(b) sensitivity

(c) current flowing through the bridge

(d) emf across the circuit

I have been asked this question during an interview.

This is a very interesting question from Sensitivity of Wheatstone Bridge in division Measurement of Resistance of Electrical Measurements

Answer 1

The correct choice is (b) sensitivity

For explanation I would say: The amount of deflection of the galvanometer depends upon its sensitivity. Resistance of the ratio arms does not affect the amount of deflection of the galvanometer.
