An inductor of inducance 5.0 H, having a negligible resistance, is connected in series with a `100 Omega` resistor and a battery of emf 2.0 V. Find the potential difference across the resistor 20 ms after the circuit is switched on.

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Identify the given values
- Inductance (L) = 5.0 H
- Resistance (R) = 100 Ω
- EMF of the battery (E₀) = 2.0 V
- Time (t) = 20 ms = 20 × 10⁻³ s
