Direction: Fig. shows the statement for given question.
-
Current i at t = 0.5 sec will be—
-
- 5 amp
-
5 amp 3 - 3 amp
-
3 amp 5
Correct Option: A
At t = 0.5 sec
30 u (t + 1) → exist and equal to 30 V
2 u (1 – t) → exist and equal to 2 amp. 
Now, we will draw the equivalent circuit under this situation we get this situation is same as the above question so,
I = 5 amp.
