You are given a length of uniform heating wire made of nickel-chromium-iron alloy called Nichrome, it has a resistance R of `72 Omega`. At what rate is energy dissipated in each of the following situations? (1) A potential difference of 120V is applied across the full length of the wire (2) The wire is cut in half, and a potential difference of 120V is applied across the length of each half.

Explanation

To solve the problem step by step, we will calculate the rate of energy dissipation (power) in two situations involving a Nichrome wire with a resistance of 72 ohms.

### Step 1: Calculate Power for the Full Length of the Wire
1. **Identify the given values**:
- Resistance of the wire, \( R = 72 \, \Omega \)
- Potential difference, \( V = 120 \, V \)

2. **Use the formula for power**:
