Practicing Success
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. Choose the correct answer from the options given below: |
E, C, A, D, B E, A, C, B, D E, D, B, A, C E, C, A, B, D |
E, A, C, B, D |
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. |
