Use of mutual induction
a. Transformers are works on this principle.
b. An inductance furnace makes use of it.
c. Used in ignition coils of motor car, motor cycles, scooters etc.
Use of self-induction
a. In regulators to give reduced voltage to the fans.
b. In fluorescence tube light to give high voltage at the time of starting and to give law voltage at it’s normal working time.
c. Used in welding plant rectifiers to keep arc stationary by smoothing choke.
