Question

The voltage sensitivity of a moving coil galvanometer, where G is the resistance of the galvanometer coil, is given by:

पर्याय

• \[\tau = N I A B \sin\theta\]

• \[\frac{\phi}{V}=\frac{NAB}{CG}\]

• \[\frac{I}{\phi}=\frac{C}{NAB}\]

• \[\frac{\phi}{I}=\frac{NAB}{C}\]

Answer 1

Voltage sensitivity is deflection per unit voltage: \[VS = \frac{\phi}{V} = \frac{NAB}{CG}\] obtained by dividing the current sensitivity expression by the coil resistance \(G\). Its unit is div/V.
