The `SI` unit of inductance the Henry can not be written as :

Options

A. weber/ampere
B. volt-second/ampere
C. `"joule"//("ampere")^(2)`
D. ohm/second

Answer

D

Explanation

(A) `L = (phi)/(i)` or Henry `= ("Weber")/("Ampere")`
(B) `e = -L ((di)/(dt)) :. L = (e)/(di//dt)`
or Henry `=("Volt - second")/("Ampere")`
(C) `U = (1)/(2) Li^(2) :. L = (e)/(di//dt)`
or Henry `= ("Joule")/(("Ampere")^(2))`
(D) `U = (1)/(2) Li^(2) = i^(2) Rt :. [L] = [Rt]`
or Henry = ohm-second.
