2) What is the unit of inductance?

Joule

Farad

Henry

Watts

Answer is:

Henry

Explanation:

Henry is the unit of either self-inductance or mutual inductance, abbreviated as H, and named for the American physicist Joseph Henry.

Material of the coil

Diameter of the coil

Frequency of the current

Current flow through the coil

Answer is:

05 H

10 H

15 H

25 H

Answer is:

Coupling

Induction

Self induction

Mutual induction

Answer is:

Weber / metre²

Weber / metre

Ampere turns / Weber

Ampere turns / metre²

Answer is:

Explanation:

Reluctance is magnetomotive force per unit flux,
So unit of reluctance = unit of MMF / unit of magnetic flux = A/Wb. = Ampere turns / Weber
