The unit of inductance is
Updated On: Jul 29, 2022
- $ \frac{\text{volt}}{\text{ampere}} $
- $ \frac{\text{joule}}{\text{ampere}} $
- $ \frac{\text{volt-second}}{\text{ampere}} $
- $ \frac{\text{volt-ampere}}{\text{second}} $
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Induced emf, $ e=L\frac{di}{dt} $ $ \Rightarrow $ $ L=\frac{e}{di/dt} $ Unit of inductance $ L=\frac{volt}{amp/s} $ $ =\frac{volt-\sec }{amp} $

Concepts Used:
Electromagnetic Induction
Electromagnetic Induction is a current produced by the voltage production due to a changing magnetic field. This happens in one of the two conditions:-
- When we place the conductor in a changing magnetic field.
- When the conductor constantly moves in a stationary field.
Formula:
The electromagnetic induction is mathematically represented as:-
e=N × d∅.dt
Where
- e = induced voltage
- N = number of turns in the coil
- Φ = Magnetic flux (This is the amount of magnetic field present on the surface)
- t = time
