AMPERE'S CIRCUITAL LAW

A

`intB*dI=mu_(0)(l)_("net")`

B

`intB*dI=mu_(0)l`

C

`intB*dI=mu_(0)//l`

D

`intB*dI=(mu_(0))/(q)`

Text Solution

Verified by Experts

The correct Answer is:
A
According to ampere's circuital law line integral of magnetic field B around any closed path or circuit is equal to `mu_(0)` times the total current crossing the area bounded by closed path provided the magnetic field insie the loop remains constant.
`intB*dI=mu_(0)(l_("net"))`
