Vedclass · Answer

(A) The self-inductance $L$ is defined by the relation $\phi = LI$,where $\phi$ is magnetic flux and $I$ is current. Thus,$L = \frac{\phi}{I}$.Units of $L$ are $\frac{	ext{weber}}{	ext{ampere}}$ (Henry).Since $	ext{weber} = 	ext{volt} \cdot 	ext{second}$,the unit is also $\frac{	ext{volt} \cdot 	ext{second}}{	ext{ampere}}$.Since $	ext{volt} = 	ext{ampere} \cdot 	ext{ohm}$,the unit is $\frac{(	ext{ampere} \cdot 	ext{ohm}) \cdot 	ext{second}}{	ext{ampere}} = 	ext{ohm} \cdot 	ext{second}$.'mho-second' is not a unit of self-inductance,as 'mho' is the unit of conductance $(1/	ext{ohm})$.
