Question

Define the term electric potential. State its S.I unit.

Answer 1

Electric potential energy is the energy that is required to move a charge against an electric field. You need more energy to move a charge further in the electric field, but also more energy to move it through a stronger electric field.

Complete step by step solution:
The electric potential, or voltage, is the difference in potential energy per unit charge between two positions in an electric field. To find the electrical potential at a chosen spot, how much the electrical potential energy of an imaginary positively charged particle would change if it moved there. Just like when talked about the electric field, we don’t actually have to place a positively charged particle at the chosen spot to know how much electrical potential energy is presented.

The amount of charge that is pushing or pulling (and whether it is positive or negative) makes a difference to the electrical potential energy if the particle moved to a chosen spot. That’s why physicists use a single positive charge as an imaginary charge to test the electrical potential at any given point. The negatively charged plate was always attracted by the positive charged plates. That means the negative charged plate is taken near to the positive charged plate, it would have a little bit of electrical potential energy, and if it continues further, the positively charged plate would have more electrical potential energy. The SI unit of electric potential is volt.

Note: The SI unit of the electric potential is determined by the general formula of the electric potential. The electric potential is the amount of energy per unit charge. By this statement the SI unit of the electric potential is determined.
