An inductor of 10mH is connected to a 18V battery through a resistor of 10k`Omega` and a switch After a long time, when the maximum current is set up in the circuit, the current is switched off. Calculate the cur- rent in the circuit after 2 `mu`s.

Explanation

To solve the problem step by step, we will follow the outlined procedure based on the information provided.

### Step 1: Identify the given values
- Inductance (L) = 10 mH = \(10 \times 10^{-3}\) H
- Voltage (V) = 18 V
- Resistance (R) = 10 kΩ = \(10 \times 10^{3}\) Ω

### Step 2: Calculate the maximum current (I₀)
