A solenoid of inductance 50 mH and resistance 10 Omega is connected to a battery of 6V. Find the time elapsed before the current acquires half of its steady - stae value.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify Given Values
- Inductance (L) = 50 mH = 50 × 10^(-3) H
- Resistance (R) = 10 Ω
- Voltage (V) = 6 V

### Step 2: Calculate the Steady-State Current (I₀)
