It is only for our convinience. Electric Potential can be taken by using any point.

Do electron moves up or fall down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
Do charges in an electric circuit flow because of a difference in electrical potential energy?
"voltage" (also referred to as 'potential')
Why under static condition all points in a conductor must be at the same electric potential?
If there is any difference of potential (a voltage), charges will flow, until all differences of potential are evened out. This is similar to water in a bowl having a flat surface: if there is any elevation, water will flow from higher to lower places, until no point is higher than others.
What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
What will you do if the world runs out of petrol diesel and others?
Walk, bicycle, drive electric cars. There is always a way to get from point A to point B.
What is electro static potential at a point?
it is defind as the amount of work done to bring a unit positive charge from infinity to that point in the electric feild it is devoted by V .: electric potential = workdone/charge V=w/q si unit is v
How is gravitational potential energy created?
It is created when a body of unit mass is brought from infinity to that point without acceleration.
Does absolute potential energy both zero and negative at point of infinity?
There is really no such a thing as "absolute potential energy"; potential energy refers to the difference in energy between two points. For purposes of calculation, a convenient reference point is often chosen, and one such reference point is a point at an infinite distance.
What is single electrode potential?
An electrode potential is the potential difference that develops when an electrode of one element is placed in a solution containing its ions. In a galvanic cell, electricity is produced by the electrode potential of the two metal electrodes and their corresponding electrolytes.
Do electrons move up or down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
Why is the potential at a point a scalar quantity?
Because the potential energy consumed or released when a charge is moved from any point to any other point (in an unchanging electric field) is independent of the path. Therefore the potential at any point is represented by a single number (of volts, if you like). If it's a single-number function of position, it's a scalar that has no direction. The gradient of the potential function on the other hand is a vector, the electric field.
Do electron moves up or fall down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
In an electric field 0.90 J of work is required to bring 0.45 C of charge from point A to point B. What is the electric potential difference between points A and B?

What does potential diffrence mean?
Potential Difference is the difference in electric potential energy per coulomb of charge at one point of a circuit compared to the charge at another point in a circuit. Potential difference, or voltage, is a way of describing the energy of an electric field without using test charges. In circuits, potential difference is the difference in voltage from one part of a circuit to another. It can also be described by ohms law where the Voltage=Current*Resistance In electrostatics, potential difference is the line integral of the electric field from one point to another with respect to distance.
What is volt of electricity?
Voltage is the measure of the electric potential difference between two points in an electric circuit. It is the amount of potential energy per unit charge available to move electrons from one point to another. Voltage is measured in units called volts, symbolized by the letter V.
What is the difference between electric potential and electric potential energy?
Electric potential energy is electric energy that is stored in a battery. so all the energy it creates is stored within the battery. It doesn't get used until someone uses it.=Electric potential is the amount of electric potential energy per one coulomb of charge at one point in a circuit compared to the potential energy per one coulomb of charge at another point in circuit also called voltage.=
The work done in bringing a unit positive charge from infinity to certain point keeping the unit charge in equilibrium is called?
Potential difference
