Henry is the unit of:
- A
Self inductance only
- B
Mutual inductance only
- C
Both Options A and B are correct
- D
E.M.F
Inductance, in general, has an SI unit “Henry” (H). Since self and mutual inductance are types of inductance, therefore both will have the same SI unit. Hence, option C is correct.
The unit of self inductance is Henry (H). Self inductance refers to the property of an electrical conductor or coil to oppose any change in the current flowing through it by generating an induced electromotive force (EMF) in the same conductor.
The unit of mutual inductance is also Henry (H). Mutual inductance is the property of two or more coils or conductors to induce an EMF in each other when the current in one coil changes. It measures the extent to which a changing current in one coil induces a voltage in another nearby coil.
Inductance, in general, has an SI unit "Henry" (H). Since self and mutual inductance are types of inductance, therefore both will have the same SI unit. Hence, option C is correct.
The unit of E.M.F is volt. Hence it is an incorrect option.
