That's just in convention, in line with other electric convention. It is common to use positive charges as a standard; for example, a current is usually defined as a movement of positive charges. If the actual charges happen to be negative (for example, electrons), the "conventional current" simply flows in the direction opposite to the flow of electrons.

Why the current flow from higher potential to lower potential?
Current defined as Positive charge flow , flows from higher potential to the lower. Current defined as electron flow, flows from lower potential to higher. In general Potential and Current are defined by positive charge.
Electric field is positive or negative?
Did you mean "The strength of electric field is positive or negative"? Anyway, there is your answer.. The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.
Which term describes the energy per unit charge in a circuit?
The SI unit of electric charge is called the coulomb. It is a derived unit, and is defined as the amount of charge moved by a steady state current of one ampere for one second. Alternatively, it is defined as the amount of charge across a capacitance of one farad charged to a potential of one volt. In terms of elementary charge, from nuclear physics, it is defined as the charge represented by about 6.24150965 x 1018 protons or electrons.
What is the voltage at the location of a Coulomb charge that has an electric potential?
A positive test charge of 1.6 x 10-11 C is placed in an electric field The force acting on it is 3.2 x 10-4 N What is the magnitude of the electric field intensity at the point where the charge is placed
What are factors that determine the size of the electric potential and electric potential energy?
Mass and Charge
Why the current flow from higher potential to lower potential?
Current defined as Positive charge flow , flows from higher potential to the lower. Current defined as electron flow, flows from lower potential to higher. In general Potential and Current are defined by positive charge.
Which physical property is defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential?
Capacitance
What is the definition for positive charge?
having a deficiency of electrons ;having a higher electric potential
What is the electric field?
The electric field is defined as the force per unit positive charge that would be experienced by a stationary point charge at a given location in the field.

Describe an electric field?
The electric field is defined as the force per unit positive charge that would be experienced by a stationary point charge at a given location in the field.
What is the flow of electricity charge?
it is the rate at which electric charges pass though a conductor. The charged particle can be either positive or negative. In order for a charge to flow, it needs a push (a force) and it is supplied by voltage, or potential difference. The charge flows from high potential energy to low potential energy.

What has positive electrical charge?
A proton has a positive electric charge.
What are the kinds of electric charge?
The kinds of electric charge are positive charge and negative charge
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
