A 16 ohm resistance wire is bent to form a square. A source of emf 9 volt is connected across one of its sides. Calculate the potential difference across any one of its diagonals.

Explanation

To solve the problem step by step, we will follow the reasoning provided in the video transcript.

### Step 1: Understand the Setup
We have a wire with a total resistance of 16 ohms that is bent to form a square. The wire is connected to a 9-volt battery across one of its sides.

### Step 2: Calculate the Resistance of Each Side of the Square
Since the wire is bent into a square, each side of the square will have an equal length. The total length of the wire is divided into four equal parts.
