Explanation: The electric potential is the ratio of work done to the charge. Also it is the work done in moving a unit positive charge from infinity to a point in an electric field.The electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field.The correct answer is Electrical Capacitance. The Electrical Capacitance is expressed as the ratio of charge to a potential difference and its SI unit is Farad. Capacitance is expressed as the ratio of the electric charge on each conductor to the potential difference between them.

(d) is directly proportional to the square of distance from the point charge.
What is the electric potential of a point charge?
Electric potential of a point charge is V=kQ/r V = k Q / r . Electric potential is a scalar, and electric field is a vector. Addition of voltages as numbers gives the voltage due to a combination of point charges, whereas addition of individual fields as vectors gives the total electric field.

Electric potential at a point is the amount of work done in bringing a unit positive charge from infinity to that point.
What is relation between electric field and potential?
If the charge is uniform at all points, however high the electric potential is, there will not be any electric field. Thus, the relation between electric field and electric potential can be generally expressed as – “Electric field is the negative space derivative of electric potential.”

Answer/Explanation
If some charge is present inside the region then electric field cannot be zero at that region, for this V=constant is not valid.
Which type of quantity is electric potential?
Electric force and electric field are vector quantities (they have magnitude and direction). Electric potential turns out to be a scalar quantity (magnitude only), a nice simplification.
What do you mean by electric potential at a point Class 12?

What is electric field and electric potential write its SI unit?
F is the force. Q is the charge. The S.I unit of electric field is V/m. The magnitude of electric potential is the amount of work done in moving a point charge from one point to another against the electric field with negligible acceleration. The SI unit of electric potential is Volts.
What do you mean by electric potential energy?
Electric potential energy is the energy that is needed 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.
What is the potential energy of a point charge in an external electric field?
Potential energy of a charge in external electric field
For a region where electric field exists and electric potential is given by V, electric potential energy of a point charge Q is given by U=QV. Example: A body of mass 1kg and charge 1C is accelerated from rest by a potential difference of 1V.
How much is the electric potential of a charge at a point at infinity?
Note: The electric potential is at infinity is zero (as, r = ∞ in the above formula).
How does electric potential due to a point charge vary with distance from it?
Electric potential is inversely proportional to the square of the distance from the centre of the dipole (i.e. V ∝ 1 r 2 ). Where as the potential due to point charge is inversely proportional with the distance from the charge (i.e. V ∝ 1 r ).
What is a potential field?
A potential is a scalar field that describes the potential energy per unit of some quantity due to a vector field. It is closely related to potential energy.
What is potential difference at a point?
Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. **Measured in Volts: **Potential difference (p.d.) is measured in volts (V) and is also called voltage.
What is the difference between electric potential and electric field?
1. Electric field is described as the amount of force per charge while the Electric potential is described as the amount of energy or work per charge. 3. Electric field is a vector quantity while Electric potential is a scalar quantity.

How are electric potential and electric potential energy related?
While electric potential energy has a dependency upon the charge of the object experiencing the electric field, electric potential is purely location dependent. Electric potential is the potential energy per charge.
Where is the electric potential zero?
The electric potential is zero at an infinite distance from the point charge. For two opposite charges of equal magnitude, the electric potential is zero in the middle since the electric field between both the charges will be equal and opposite.
