It is the work done to moving a unit positive charge or test charge from one to another point in electric field this work done is called the potential difference.
The work measure is Joule or electron volt.

Voltage
The guy that descovered the formula for power (work/time = power) had the last name "watt"AnswerIn SI, compound units are frequently given special names. For example, the coulomb is a special name given to an ampere second.Power is the rate at which energy is supplied and, so, its compound unit is the joule per second. Under SI, this is given the special name, 'watt', in honour of a Scottish engineer, James Watt.

Work is said to be done where certain displacement is involved. Ex. Of work not done is Coolie carrying Load on his head..
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
The potential difference ('voltage') is equal to the work done per unit charge, i.e. the energy given to each Coulomb of charge. So, a six Volt battery provides six Joules of energy to each Coulomb of charge.
The electric potential energy of given configuration of charges is defined as the work which must be done against the Coulomb force to rearrange charges from infinite separation to this configuration (or the work done by the Coulomb force separating the charges from this configuration to infinity). For two point-like charges Q1 and Q2 at a distance r this work, and hence electric potential energy is equal to: E_mathrm{p,e} = frac{1}{{4piepsilon_0}}{{Q_1Q_2}over{r}} ============================================ Yes, yes, undoubtedly correct. But what is an electrostatic force ? Atraction between two opposite forces

It is usually called a panel or series.
It is usually called a panel or series.
potential difference between two points equals the Work done to get to from A to B (in Joules) divided by the charge in Coulombs of the particle that is moving from A to B. If the particle was 1.60x10^-19 Coulomb, then the EPdifference, in Volts, is about 2.5. Volts is Joules/Coulomb. Think of it in terms of regular gravitational potential energy, where the potential energy is equivalent to the amount of force done to move an object of a certain weight (think coulomb) a certain distance (force over a distance is Work in Joules).
If you're given 'power', then you don't even need to know the 'mass'.Work done = (power) multiplied by (length of time it continued)
Energy!
Energy
a part of the energy that is transferred to the load is lost in heating.Therefore actual work done by the charge will be a little less.
You cannot. You do not have the necessary information.
I am sorry but work done=energy*(multiply by) time. You have given time but not anything else. How am i supposed to calculate the energy for anything?
