Select incorrect unit of self inductance

A

Mho-second

B

`"Weber"/"Amp"`

C

`"Volt-Second"/"Ampere"`

D

Ohm-second

Text Solution

Verified by Experts

The correct Answer is:
A
From `L=(N phi)/I`, unit = `"Volt"/"Amp"`
From `E=-L , (dI)/(dF) rArr L=-epsilon/(dI//dF)`
unit of L `"Volt-sec"/"Amp"`
`"Volt"/"Amp"`=ohm
Unit of L = ohm.sec
`therefore` mho-sec is not unit of self inductance.
