The deflection of the pointer in a moving iron instrument is proportional to

Right Answer is:

The current squared

SOLUTION

  • In a moving iron instrument, the pointer’s deflection is proportional to the square of the current (I²).
  • This indicates that if you double the current, the deflection will increase by four times.
  • The deflection of the pointer is influenced by the magnetic field created by the coil, which is directly related to the current flowing through it.
