==Key Stage 5==
===Meaning===
'''Charge carriers''' are [[Electrical Charge|charged]] [[particle]]s that move through a [[substance]] when a [[Potential Difference|potential difference]]]] (pd) is applied across it.
===About Charge Carriers===
*In [[metals]], the '''charge carriers''' are [[electron]]s.
*In [[electrolyte]]s, the '''charge carriers''' are [[ion]]s.
*The movement of '''charge carriers''' constitutes an [[Electrical Current|electric current]].
*In [[semiconductor]]s, '''charge carriers''' include both [[electron]]s and [[Electron Hole|holes]].
*The concentration and mobility of '''charge carriers''' affect the [[Electrical Conductivity|electrical conductivity]] of a [[material]].
'''Charge carriers''' are fundamental in the operation of electronic devices such as [[transistor]]s and [[diode]]s.
*Understanding '''charge carrier''' dynamics is crucial for designing and optimizing electrical and electronic systems.
===Examples===
*In a copper wire, the free [[electron]]s act as [[Electrical Charge|charge]] carriers.
*In a solution of saltwater, the sodium and chloride ions act as [[Electrical Charge|charge]] carriers.
