When a potential difference of 2 volt is applied across the ends of a wire of 5 m length, a current of 1 A flows through it. Calculate :
the resistance across the ends of the wire if it is doubled on itself.

Explanation

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

### Step 1: Identify the given values
- Potential difference (V) = 2 volts
- Current (I) = 1 ampere
- Length of the wire (L) = 5 meters

### Step 2: Calculate the resistance of the wire using Ohm's Law
