component

Chemistry

A distinct chemical species in a mixture. If there are no reactions taking place, the number of components is the number of separate chemical species. A mixture of water and ethanol, for instance, has two components (but is a single phase). A mixture of ice and water has two phases but one component (H₂O). If an equilibrium reaction occurs, the number of components is taken to be the number of chemical species minus the number of reactions. Thus, in
$H_{2} + I_{2} ⇌ 2 HI$
There are two components. See also phase rule.

Chemical Engineering

A constituent in a mixture that is defined as a phase or as a chemical species. See gibbs’ phase rule.

Electronics and Electrical Engineering

A discrete packaged electronic element, such as a resistor, that performs one electrical function. Primarily active electronic elements are usually termed devices and passive ones are component parts.
