Which two of the three wires of a household circuit are at the same potential ?

Explanation

To determine which two of the three wires in a household circuit are at the same potential, we need to understand the function of each wire.

1. **Identify the three wires in a household circuit:**
- The three wires typically found in a household circuit are:
- **Live wire (or phase wire)**: This wire carries the current to the load and is at a high potential.
- **Neutral wire**: This wire completes the circuit by carrying current away from the load and is typically at a potential close to zero.
- **Earth wire (or ground wire)**: This wire is a safety feature that prevents electric shock by providing a path for fault current to flow to the ground.
