In a PMMC meter, the pointer's movement is directly proportional to:

Right Answer is:

The current flowing

SOLUTION

  • In a PMMC meter, the pointer’s movement is directly linked to the current flowing through the coil.
  • The more current, the greater the pointer’s deflection.
  • Springs then ensure the pointer returns to zero when there’s no current.
  • Because of this direct relationship, PMMC meters have a linear scale, making readings straightforward.
