Watts, Volts and Amperes are basic units of measure for a DC (Direct current) power supply. A battery, for example, is a direct current power supply and the combined measure Volts x Amps = Watts.
Watts are important because watts represent the electrical energy spent by a battery (power generator) and used by an electrical device. Watts in effect is the measure of the amount of work done by a certain amperage (amount) of electric current at a certain pressure or voltage.
Voltage is the amount of "pressure" of electrons as the electrons pass from a negative connector to a positive connector.
Amperes (commonly "Amps" ) is a measurement of quantity of the number of electrons passing through a given wire per second.
How many electrons are in an Ampere?
A lot: 62,000,000,000,000,000,000 electrons per second!
