Vedclass · Answer

(D) The formula for inductance $L$ is given by $\phi = LI$,where $\phi$ is magnetic flux and $I$ is current. Thus,$L = \phi / I$. The unit of magnetic flux is $weber$ $(Wb)$ and current is $ampere$ $(A)$. So,$1 \ henry = 1 \ Wb/A$. This matches option $A$.Since $V = -L(dI/dt)$,we have $L = V(dt/dI)$. The units are $volt \cdot second / ampere$. This matches option $B$.The energy stored in an inductor is $U = (1/2)LI^2$,so $L = 2U/I^2$. The unit of energy is $joule$ $(J)$. So,$1 \ henry = 1 \ J/A^2$. This matches option $C$.Option $D$,$ohm-meter$,is the unit of resistivity,not inductance. Therefore,the henry cannot be written as $ohm-meter$.

The $SI$ unit of inductance,the henry,cannot be written as:
