Question
Use Multisim to simulate the circuit shown below. At t=0, both switch, SW1. and switch, SW2, change. You will not need to include the switches in your simulation. You should perform a transient simulation in which you set inductor L2 to have the correct initial current. To help you start, there is a file in the Skills Challenge directory called InductorSim.ms11. Use Multisim to determine the final steady-state current value for current i3. In other words, what is i3(infinity)? The answer to this question may surprise you. See if you can reason out what is happening in the circuit.Explanation / Answer
After simulation we see i3(infinite) = 0;
Here, the current source is giving the current that was flowing through R2, L2, before the switch over.
After the switch over the current source only supplies current to R2.
The current through L2 doesnot change suddenly, but it decays through R1, the resistive load.
So, due to connection with L2, the current i3 initially increases but due t3o the power loss in R1, i3 ultimately drops down to zero.
So, i3(infinite) = 0
