Question:

As a current is set up in a moving coil galvanometer, then arrange the following in sequential order.

A. Pointer attached with the coil starts rotating.
B. Pointer stops moving due to equilibrium between restoring torque and torque of coil.
C. The spring creates a restoring torque $\tau_c=k_\phi$.
D. Pointer reads a calibrated value.
E. The coil of the meter experience torque $\tau$ = NIAB and starts rotating.

Choose the correct answer from the options given below:

Options:

E, C, A, D, B

E, A, C, B, D

E, D, B, A, C

E, C, A, B, D

Correct Answer:

E, A, C, B, D

Explanation:

The correct answer is Option (2) → E, A, C, B, D

Following is the correct sequence.

The coil of the meter experience torque, $\tau$ = NIAB and starts rotating.

Pointer attached with coil starts rotating.

The spring creates a restoring torque, $\tau_c=k_\phi$.

Pointer stops moving due to equilibrium between restoring torque and torque of coil.

Pointer reads a calibrated value.
