Here's why:
* Neutral wire's role: The neutral wire provides a return path for the current to flow back to the source (usually the power outlet). It is typically connected to ground at the electrical panel, bringing its potential close to 0V.
* Current flow: When an appliance is switched on, current flows from the "hot" wire through the appliance and back to the source through the neutral wire.
Important Note: While the neutral wire is typically considered "ground" in most home wiring, it is not the same as the ground wire.
* Ground wire: The ground wire is a safety feature that provides a path for electrical current to safely flow to the ground in case of a fault. It is always connected to the ground, even when the appliance is off.
