Question

Voltage sensitivity and current sensitivity are related.

(a) True

(b) False

The question was asked in an interview.

This interesting question is from Moving Coil Galvanometer topic in section Moving Charges and Magnetism of Physics – Class 12

Answer 1

The correct option is (a) True

The best I can explain: Yes, voltage and current sensitivity are related to each other. Current sensitivity

IS = \(\frac {NAB}{k}\); Voltage sensitivity = \(\frac {\theta }{V} = \frac {\theta }{IR} = \frac {NAB}{Kr}\)

Therefore, voltage sensitivity ➔ VS = \((\frac {1}{R})\) x IS.
