If `I=5A` and decreasing at a rate of `10^(2)(A//sec)` , then `V_(B)-V_(A)`

A

`5V`

B

`10V`

C

`15V`

D

`20V`

Text Solution

Verified by Experts

The correct Answer is:
C
An inductor can be replaced by battery of
`emfLdi//dt`
`e=Ldi//dt=5xx10^(-3)xx10^(30)=5V`
`V_(A)-5xx1+15+5=V_(B) implies V_(B)-V_(A)=15V`
