The shunt magnet of an induction energy meter carries a winding of

  • A.many turns of thick wire connected in series with the load current
  • B.few turns of fine wire connected between the disc spindle and earth
  • C.many turns of fine wire connected across the supply
  • D.few turns of thick wire connected in series with the load

Answer: C

The shunt magnet is the pressure element and its winding is highly inductive, so its flux is nearly proportional to the voltage and lags it by close to ninety degrees. The series magnet carries the load current in a few thick turns.
