==Key Stage 4==
===Meaning===
[[File:ThermistorSymbol.png|right|300px|thumb|The symbol for a '''thermistor'''.]]
A '''thermistor''' is a [[resistor]] which changes [[Electrical Resistance|resistance]] depending on the [[temperature]].
===About Thermistors===
: 'NTC' '''thermistors''' decrease [[Electrical Resistance|resistance]] as the [[temperature]] increases.
: A '''thermistor''' can be used to control the [[Electrical Current|current]] passing through a [[circuit]]. If the [[Potential Difference|potential difference]] is constant then the [[Electrical Current|current]] decreases as [[temperature]] decreases.
: A '''thermistor''' can be used to control the [[Potential Difference|potential difference]] of another [[Electrical Component|component]] in [[Series Circuit|series]] with it. If the [[temperature]] is decreased then the [[Potential Difference|potential difference]] across other [[Electrical Component|components]] will decrease.
: '''Thermistors''' can be used [[temperature]] sensors.
