In the SI standard for physics units (see NIST website,) quantities of electricity are measured in coulombs, same as the quantity of electric charge.
A quantity is an amount, or how much there is of a given thing. In this case, a quantity of electricity would be the amount of electricity used in a given reaction.
The difference between quantity and unit in "16 pounds" is the unit is pounds and the quantity is 16.
The coulomb is the SI unit of measure of electric charge, equal to the quantity of electricity conveyed in one second by a current of one ampere.
A standard use for a measurement of a physical quantity is called the unit of that physical quantity
The term, 'electricity', is a generic, all-encompassing term for a branch of science. Electricity, therefore, isn't a quantity, so it cannot be measured.A megawatt is an unit of measurement for power, the rate of transfer of energy.
A Coulomb is the SI unit of electric charge, equal to the quantity of electricity conveyed in one second by a current of one ampere.
'Electricity' is not a quantity, it's a topic. So 'emitting electricity' is quite meaningless. You need to rephrase the question to specify what quantity you are actually referring to when you say 'electricity'.
If this question is asking about the box supplied by your utility company which counts the kilowatt.hours you used, so they can send you a bill for electricity, it is called an electricity meter. If you are asking about the name of the standard unit used to measure a quantity of electricity used, it is called the kilowatt.hour (or k.Wh for short.)
First LawThe quantity of a substance produced by electrolysis is proprotional to the quantity of electricity used. Second LawFor a given quantity of electricity the quantity of substance produced is proportional to its weight.
It is a unit rate.A unit rate.
The quantity of matter per unit volume is the density.
