joule A measure of work or energy. One joule of energy produces one watt of power for one second.
junction point the location where a circuit divides into multiple paths or where multiple paths combine.
kilowatt-hour A unit of electric energy equal to the work done by one kilowatt acting for one hour.
parallel circuit A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit.
power (physics) the rate of doing work
