What actually is voltage

i know all the fancy definitions but what actually is voltage.

i mean i know that current is when electrons pass through the wire.

but what is voltage. is voltage the concentration of electrons on one end which have the potential to move to the other positive end.

and how can we explain the power consumption principle in simple terms that power = voltage × current. where increasing voltage decreases current.
how is that possible? i thought higher voltage meant higher current.

don't understand it yourself.”

To a six year old I would say it is the amount of push given to the lumps of electricity.

Voltage is the energy of a unit's worth of electrons. But as usual, what we are really interested in is energy difference. So a voltage is the difference in energy that a unit's worth of electrons in one location has compared to another location. It is a bit like defining the height of something as the difference in potential energy of a 1kg mass at the top compared to the bottom.

Since energy likes to balance out where it can, electrons at the high energy end "like" to travel to the low energy end if they can.

Power is the rate of use of energy. So the electric power "used" between two points is basically the difference in their energy levels (voltage) multiplied by the amount of electrons moving between them (current).

A higher voltage (energy level) obviously requires less electrons (current) to transport the same amount of energy.

well, we are all familiar with flow of current through wires. similar to flow of current we also are familiar with flow of heat, wind, water too. if any thing is to flow a difference of some quantity is always required. thus temperature difference is needed for heat flow, pressure difference is needed for blowing of wind and difference of level is needed for flow of water. similarly, a difference of voltage is needed for flow of current and always current flows form higher voltage to lower voltage.
