what is Electrical potential
Answers
Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Typically, the reference point is Earth, although any point beyond the influence of the electric field charge can be used. Electric potential.
Answer:
Explanation:
When an object is moved against the electric field it gains some amount of energy which is defined as the electric potential energy.
For any charge, the electric potential is obtained by dividing the potential energy by the quantity of charge.
An electric potential is the amount of work needed to move a unit of charge from a reference point to a specific point inside the field without producing an acceleration.
Typically, the reference point is the Earth or a point at infinity, although any point can be used.
SI unit: volt
Other units: statvolt
In SI base units: V = kg⋅m2⋅A−1⋅s−3
Common symbols: V, φ
Dimension: M L2 T−3 I−1

Additional information ❤
The electric force F exerted by the field on the positive charge is F = qE; to move the charge from plate A to plate B, an equal and opposite force (F′ = −qE) must then be applied.
The work W done in moving the positive charge through a distance d is W = F′d = −qEd.
