The potential difference across a 2-H inductor as a function of time is shown in Fig. At time t = 0, current is zero.

Current at t = 1 s is

A

`1 A`

B

`2 A`

C

`4 A`

D

`8 A`

Text Solution

Verified by Experts

The correct Answer is:
B
From explantion on privious page
`L(i_(f)-i_(i))`= are under `V_(L)-t` graph
`2(i_(f)-0) = 1/2 xx 1 xx 8 = 4`
`i_9f=2A`.
