Question

The unit of inductance is

• A. $\frac{\text{volt}}{\text{ampere}}$
• B. $\frac{\text{joule}}{\text{ampere}}$
• C. $\frac{\text{volt-second}}{\text{ampere}}$
• D. $\frac{\text{volt-ampere}}{\text{second}}$

Answer 1

Answer: (C)

$\frac{\text{volt-second}}{\text{ampere}}$

Answer 2

Induced emf, $e=L\frac{di}{dt}$ $\Rightarrow$ $L=\frac{e}{di/dt}$ Unit of inductance $L=\frac{volt}{amp/s}$ $=\frac{volt-\sec }{amp}$
