Physics for IGCSE & O level - Electricity (Section 4 - No. 40)
What is the main difference between a live wire and a neutral wire?
The live wire carries the current back to the source, while the neutral wire provides insulation.
The live wire is at a high voltage, while the neutral wire is at a low voltage (or close to zero).
The live wire is thinner, while the neutral wire is thicker.
The live wire is always connected to the earth.
Açıklama
The live wire is at a higher voltage, providing the electrical potential, while the neutral wire is at a lower potential.
