Question

Current sensitivity of a galvanometer is defined as the:

पर्याय

• Deflection produced per unit current

• Torque produced per unit resistance

• Deflection produced per unit voltage

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

Answer 1

Current sensitivity measures how much deflection \(\phi\) is produced for each unit of current \(I\). It equals \[CS = \frac{\phi}{I} = \frac{NAB}{C}\] and is expressed in div/A or div/μA.
