What happens to the coil in a PMMC meter when no current flows through it?

Right Answer is:

It remains stationary at the zero position

SOLUTION

  • The hairsprings attached to the coil provide a restoring torque that returns the coil to its initial position when there is no current.
  • These springs resist the movement of the coil and ensure it goes back to the zero mark when the current
