Question

The $\text{SI}$ unit of inductance, $\text{henry}$, can be written as

• A. $\text{Wb/A}$
• B. $\text{V-s/A}$
• C. Both options $\left(A\right)$ and $\left(B\right)$
• D. None of these

Answer 1

The correct option is C Both options $\left(A\right)$ and $\left(B\right)$

We know that,

$L=\frac{N\varphi }{I}$

Hence, the $\text{SI}$ unit of $L$ can be written as $\text{Wb/A}$.

Also,

$E=-L\left(\frac{dI}{dt}\right)$

$\Rightarrow L=-\frac{E}{\frac{dI}{dt}}=-\frac{Edt}{dI}$

Hence, the $\text{SI}$ unit of $L$ can be written as $\text{V-s/A}$.

Therefore, option $\left(C\right)$ is the correct answer.
