Question

8.
What is formula of electric potential?​

Answer 1

Answer:

In an electrical circuit, the potential between two points (E) is defined as the amount of work done (W) by an external agent in moving a unit charge (Q) from one point to another.

Mathematically we can say that, E = W/Q.

Answer 2

Explanation:

Electric Potential Formula

Method 1:

Electric Potential Formula

The electric potential at any point around a point charge q is given by:

V = k × [q/r]

Where,

V = electric potential energy,

q = point charge,

r = distance between any point around the charge to the point charge,

k = Coulomb constant; k = 9.0 × 109 N.

Method 2: Using Coulomb’s Law

Electrostatic Potential Formula

The electrostatic potential between any two arbitrary charges q1, q2 separated by distance r is given by Coulomb’s law and mathematically written as:

U = k × [q1q2/r2]

Where,

U is the electrostatic potential energy,

q1 and q2 are the two charges.

Note: The electric potential is at infinity is zero (as, r = ∞ in the above formula).
