Explanation:
- The electric field is represented by the symbol E. The SI unit of the electric field is newton per coulomb which is equal to volts per meter.
Electric current is defined as the rate at which charge flows through a surface (the cross section of a wire, for example). Despite referring to many different things, the word current is often used by itself instead of the longer, more formal "electric current". The adjective "electric" is implied by the context of the situation being described. The phrase "current through a toaster" surely refers to the flow of electrons through the heating element and not the flow of slices of bread through the slots.
The unit of current is the ampère [A], which is named for the French scientist André-Marie Ampère (1775–1836). In written languages without accented letters (namely English) it has become customary to write the unit as ampere and, in informal communication, to shorten the word to amp. I have no problem with either of these spellings. Just don't use a capital "A" at the beginning. Ampère refers to a physicist, while ampère (or ampere or amp) refers to a unit.
An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called "electrical charge") flow.
