Question : 164 of 200

Marks: +1, -0

In the given circuit, find the current I in the 3-kΩ resistor at time t = 2 sec.

4 mA
2 mA
4 A
2 A

Solution:

At time t = 2 secFirst switch will be in the open condition because it closes at 5th second
Second switch will be in a closed state because it gets opened at 3rd second.
So circuit at t = 2 s reduces to

∴ i =6 / 3000 \A

i = 2 \m \A
