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 |
power rating | a measurement of how much electrical energy an electrical device consumes for every second it is in use. |
series circuit | A circuit in which all parts are connected end to end to provide a single path of current. |
watt | A measure of power equal to one joule of work per second. |
