Question

The SI unit of inductance, the henry can be written as

• A. $\frac{weber}{Ampere}$
• B. $\frac{Voltsecond}{Ampere}$
• C. $\frac{Joule}{Amper{e}^2}$
• D. All the above

Answer 1

The correct option is D

All the above

S.I. unit of inductance:

1. The S.I. unit of inductance is henry.
2. Inductance can be written as the ratio of magnetic flux to the current flowing. So, the unit, henry can be written as $\frac{weber}{Ampere}$.
3. The unit weber can be written as the product of volt and second, so the unit, henry becomes $\frac{Voltsecond}{Ampere}$.
4. Inductance can also be written as twice of energy dissipated divided bu square of current flowing, so the unit, henry can be written as $\frac{Joule}{Amper{e}^2}$.
5. Hence, all options are correct.

Thus, option D is the correct answer.
