Expert Solution

Step 1

We are authorized to answer one question at a time since you have not mentioned which question you are looking for, so we are answering the FIRST one, please repost your question separately for the remaining question.

The switch has been opened for a long time.

The circuit diagram is:

The switch is closed at t = 0. The inductor does not allow the sudden change in the current.

Step 2

At steady-state, the inductor acts as short circuit.

The modified circuit is:

Applying Kirchhoff’s current law at node A:

Step 3

The value of i₃ is:

The value of the time constant of the circuit is:
