A coil of inductance 1.0 H and resistance 100 Omega is connected to a battery of emf 12 V. Find the energy stored in the magnetic field associated with the coil at an instant 10 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) = 1.0 H
- Resistance (R) = 100 Ω
- EMF (E) = 12 V
- Time (t) = 10 ms = 10 × 10^(-3) s
