When 6,250,000,000,000,000,000 electrons pass a point in one second there is one amp of current (amps) flowing through that circuit. The push (electrical pump) that causes the flow is called voltage and is created by some system that separates neutral atoms into positive and negative charges. That is done by moving the electrons (- charges) away from the atom leaving it as a (+) positive charge. A battery uses chemical action and a generator uses magnetic force. The rate at which work is done is called power and measured in watts. One watt is the product of one amp times one volt. One horsepower is the same as 746 watts. The thing to remember is that voltage is measured between two places (across) and current is measured through a conductor.
