If $E$ and $H$ represents the intensity of electric field and magnetizing field respectively, then the unit of $\dfrac{E}{H}$ will be:

Options

Ajoule
Bohm
Cnewton
Dmho

Correct answer

B. ohm

Step-by-step solution

The unit of,

\dfrac{E}{H} = \dfrac{\dfrac{F}{q}}{\dfrac{I}{r}} = \dfrac{Fr}{{I}^{2}t},

here the units are,

F = N

,

r = m

,

I = A

and

t = s

then the net unit of

\dfrac{E}{H}

,is

{\text{J s}}^{- 1}{\text{A}}^{- 2}

, which is equivalent to

Ω

.
