Question

What do you mean by zero potential?

Answer 1

1. Electric potential is defined as the amount of work needed to move a unit charge from a reference point to a specific point against the electric field.
2. An electric charge is said to be zero potential when it is infinitely far away from other charges.
3. If the charge arrangement cancels out the potential at a point then the potential at that point is said to be zero potential.
4. For electrical circuits earth is taken at zero potential.
