In the given circuit, find the current i in the 3-kΩ resistor at time t = 2 sec.
In the given circuit, find the current i in the 3-kΩ resistor at time t = 2 sec.
Right Answer is:
2 mA
SOLUTION
At time t = 2 sec
First 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 mA
