Physics
The neutral and the earth wires are connected at the local sub station so that :
- the potential increases
- the neutral and earth wires are at the same potential
- the potential of neutral wire increases
- none of the above
Answer
the neutral and earth wires are at the same potential
Reason — When the neutral and earth wires are at the same potential, it helps to stabilize the electrical system and ensures that any fault currents are safely redirected to the ground, minimizing the risk of electric shocks and other hazards to people and equipment.
