Meaning of Equivalent (What it is, Concept and Definition)

Equivalent is a two-gender adjective from French "equivalent" and expresses something that has equal value, or that has the same sense.

Thevenin equivalent

Thevenin's Equivalent consists of a theorem that makes it possible to simplify and solve an electrical circuit, since an equivalent circuit that replaces a complex network is determined.

Mechanical equivalent of heat

The mechanical equivalent of heat is a physical quantity that indicates how much heat corresponds to mechanical work, and vice versa. Its value is 4.1855 joule/calorie.

chemical equivalent

The chemical equivalent is the fraction 1/z of a chemical species (molecule or ion), in which z is an integer that indicates how many reaction units that chemical species produces in its specific acid-base, redox, or neutralization reactions. So, for example, in H2SO4, z=2, because one molecule of H2SO4 can yield 2 H+ ions.
