An LR circuit constains an inductor of 500 mH, a resistor of `25.O Omega` and an emf of 5.00 V in series. Find the potential difference across the resistor at t =(a) 20.0 ms, (b) 100 ms and ( c) 1.00 s.

Explanation

To solve the problem of finding the potential difference across the resistor in an LR circuit at different time intervals, we can follow these steps:

### Given Data:
- Inductance, \( L = 500 \, \text{mH} = 500 \times 10^{-3} \, \text{H} \)
- Resistance, \( R = 25.0 \, \Omega \)
- EMF, \( E = 5.00 \, \text{V} \)

### Step 1: Calculate the Steady State Current (\( I_0 \))
