Expert Solution
Introduction:
  • Inductors are passive components that store energy in magnetic fields. When AC current is passed through an inductor the magnetic field due to the current can cause self-induction. This will generate an emf that will oppose the current flow.

 

  • The self-induced emf on an inductor is given by,

ε=−Ldidt

Here L is the inductance and didt is the change in current.
