A^{2} 
abbreviation of "ampere" or "amperes," a unit of electrical current that refers to the quantity of current that passes through a resistor of one ohm when a potential of one volt is applied, equal to one coulomb per second. 
amp 
ampere. 
coulomb 
a unit of electrical charge equal to the charge of 6.28 times 10^{18} electrons or the charge transferred in one second by a steady current of one ampere. 
henry 
a unit of electrical inductance equal to the inductance of a closed circuit in which current varies at the rate of one ampere per second to produce an electromotive force of one volt. 
milliampere 
a unit of electrical current equal to one thousandth of an ampere. 
ohm 
a unit of electrical resistance equal to the resistance of a circuit in which an electromotive force of one volt produces a current of one ampere. 
volt^{1} 
a unit of electromotive force equal to the force that carries one ampere of current through one ohm resistance. (abbr.: V) 
voltampere 
a unit of electrical power equal to the product of one volt and one ampere, or to one watt. 
W^{4} 
abbreviation of "watt," or "watts," a unit of electrical power equal to the current of one ampere produced by the electromotive force of one volt, or to one joule per second. 
watt 
a unit of electrical power equal to the current of one ampere produced by the electromotive force of one volt, or to one joule per second. (abbr.: w, W)
