Want this question answered?
Current is produced when charges are accelerated by an electric field to move to a position of lower energy.
The device that uses chemical energy to give charges electric potential energy is a battery because it uses chemical energy which gives off potential electric charges.
No charges have to be present.
As long as there is any electric potential, charges continue moving around, until everything is balanced.
TRUE

potential energy
The device that uses chemical energy to give charges electric potential energy is a battery because it uses chemical energy which gives off potential electric charges.

Q1:How to calculate electric potential due to a dipole? Q2:How to calculate electric potential due to ring of charges? Q3:How to calculate electric potential due to charge disk? Q4:how to calculate electric potential due to a quadrupole?
An electric charge is produced when a body has deficiency or excess of electrons from the normal due share.
As long as there is any electric potential, charges continue moving around, until everything is balanced.
"voltage" (also referred to as 'potential')
In end part of the wire there is less potential charge we know that charge flow from high potential to low potential so it happenr
TRUE
TRUE
Electric potential is a scalar which means you merely add up all the potentials at the center of the cube while ignoring the direction it is pointed in. I supposed voltage (or electric potential) could be 0 if you have an even number of positive and negative charges all with the same distance from the center (if the charges are on the corners of the square the distances would in fact be the same).
