Question

The Scale used in a moving coil galavnometer is a

• A. Function scale
• B. Exponential scale
• C. Linear scale
• D. circular scale

Answer 1

The correct option is C Linear scale

Te angle through which the needle is deflected is proportional to the current in the coil, and all other quantities remains constant.

$I=\left(\frac{C}{NBA}\right)\theta$

$I\propto \theta$

so, the scale is linear.

Hence, option $\left(C\right)$ is the correct answer.
