- weber $\div$ ampere
- weber $\div$ volt
- weber ampere
- weber volt
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$E = - L \frac{dI}{dt}$ . Therefore $[L] = [E \,dt/dI]$ = volt second/ampere
= volt second/(coulomb/second)
= volt second$^2$/coulomb = joule second$^2$ / coulomb$^2$

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
