Units & Dimensions

If E and H represents the intensity of electric field and magnetising field respectively, then the unit of E/H will be:

Show answer and solution

Answer: (a)

Unit of $E$ is $\text{V/m}$ ; unit of $H$ is $\text{A/m}$ .
$\frac{E}{H} \to \frac{\text{V/m}}{\text{A/m}} = \frac{\text{V}}{\text{A}} = \Omega$
So the answer is (a) ohm.
