What are volts, amps, watts, joules, etc?
Term Measure Definition newton force The force which will give 1 kilogram of mass an acceleration of 1 meter /second^2 dyne force 1/10^5 newtons joule work The work done when a force of 1 newton acts through a distance of 1 meter. erg work 1/10^7 joules ampere electric current 1 ampere is a charge flow of 1 coulomb per second ampere electric current “that constant current which, if maintained in two straight parallel conductors in infinite length, of negligible circular cross section, and placed 1 meter apart in a vacuum, would produce between these conductors a force equal to 2×10^-7 newton per meter of length.” volt electric potential (joules per coulomb) The electromotive force required to drive a steady current of 1 ampere through a resistance of 1 ohm coulomb electric charge 1 coulomb is the charge carried across a surface by a steady current of 1 ampere in 1 second watt power 1 watt is 1 joule per second [Power is the rate of doing work.] watt-second energy 1 watt of power being
