Question

Voltage sensitivity of a galvanometer is defined as the:

पर्याय

• Deflection produced per unit voltage

• Voltage required to produce a unit deflection (1 division) on the scale

• Deflection produced per unit current

• Current required to produce full-scale deflection

Answer 1

Voltage sensitivity is the deflection produced per unit voltage applied: \[VS = \frac{\phi}{V} = \frac{NAB}{CG}\] where \(G\) is the resistance of the galvanometer coil. Its unit is div/V.
