    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) \[\frac{\text{volt-ampere}}{\text{second}}\]

    Correct Answer: C

    Solution :

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