Question

How many voltage are running on the earth??​

Answer 1

Answer:

230 volt

Typically, the voltage between earth and phase/live is 230 volt.

The voltage between neutral and phase varies from 220–230.

The voltage between neutral and earth is 0 under ideal conditions. (that's why earthing process is possible)

In practical conditions there may exist a very small potential difference

if it is useful mark it as brainliest answer

Answer 2

Explanation:

Voltage of Earth

Neutral-to-earth voltage (N-E), sometimes called “stray voltage,” is a condition that results when an electrical current flows through a neutral conductor. Most (110 volt) electric lines contain three wires- one “hot” or powered, one neutral and the ground wire.
