my answer -
Electrical pressure, called "electro-motive force" (EMF), is what causes current to flow in an electrical circuit. EMF is measured in volts. Pressure and the quantity of electricity transmitted can be considered analogous to pressure and quantity of water flowing in pipes: the longer the distance, the higher is the flow of water (called the "flow of electrical charge, which is also known as the "electric current"). That is why, for long distance transmission, high pressure (voltage for electricity) is required, failing which, the current - and therefore the power - will not reach the intended destination. Instead, it will be lost (also called "dissipate") along the way. We can think of electrical
current as the quantity of electricity which will be drawn from the pipeline
cables for electricity) at the pressure (= voltage) required.
P.S
Happy to help you have an AWESOME!!! day ^-^
