A shunt generator has its field winding

  • A.connected across the armature terminals
  • B.connected in series with the armature and the load
  • C.fed from a separate independent supply
  • D.replaced by permanent magnets in the pole shoes

Answer: A

Correct answer: connected across the armature terminals

A shunt field is connected in parallel with the armature, so it sees the terminal voltage and carries a small current - typically one to three per cent of the rated current - through many turns of fine wire. Because the excitation follows the terminal voltage rather than the load current, the shunt generator holds its voltage reasonably well as load is applied, which is why it suits lighting and battery charging.
