Question

Potential is measured in ______.

Answer 1

Electric potential is a scalar quantity and is equivalent to the electric potential energy divided by the unit charge. Work has units Joule, and charge has unit’s coulomb. Electric Potential’s unit can be obtained by the formula and its unit is equal to the Joule per Coulomb.

Complete step-by-step solution:
Electric potential is the measure of work required to move a unit charge from a starting point to a particular point facing an electric field. In electrostatics, the electrostatic field is a vector quantity displayed as the gradient of the electrostatic potential, a scalar quantity denoted by V equal to the electric potential energy of any charged location divided by the particle charge.
Objects may occupy a property identified as electric charge, and an electric field applies a force on required objects. If the charged object is positive, the force will be in the electric field vector direction at that point, while if the negative charge is there, the force will be in the reverse direction. The magnitude of the force is produced by the quantity of the charge multiplied by the magnitude of the electric field vector. Force and potential energy are related. A total net force performing on any object will make it accelerate. As an object travels in the direction in which the force accelerates it, its potential energy falls. For example, the potential energy of a ball at the peak of a hill is more significant than at the foot of the hill. As it runs downhill, its potential energy drops, being turned to kinetic energy.
Electric potential is represented by letter V. It is given by-
$V = \dfrac{W}{Q}$
Where W is the amount of work done and having units Joule(J).
Q is the charge and has units Coulomb(C).
By the above formula, Potential is measured in $JC^{-1}$ which is equivalent to the volts. At infinity, the electric potential is supposed to be zero.
Also, the potential energy for a positive charge rises when it moves facing an electric field and drops when it moves by the electric field; the opposite is valid for a negative charge. Unless the unit charge joins a changing magnetic field, its potential at any provided point is independent of the path taken.

Note: It is possible to define the potential of specific force fields so that the object's potential energy in that field depends only on its position. Two such force areas are the gravitational field and an electric field. Such fields must modify objects due to the object's intrinsic properties and the object's position.
