MCQ
Choke coil works on the principle of
  • A
    Transient current
  • Self induction
  • C
    Mutual induction
  • D
    Wattless current

Answer

Correct option: B.
Self induction
b
The choke coil works because it acts as an inductor. When the current passing through changes, as $AC$ currents do, it typically creates a magnetic field in the coil that works against that current. This property, known as inductance.
