===About Thermistors===
: 'NTC' '''thermistors''' decrease [[Electrical Resistance|resistance]] as the [[temperature]] increases.(NTC = Negative Temperature Coefficient.)
: 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.

====Description====
The '''IV graph''' for an 'NTC' [[thermistor]] shows that:
*At a high [[temperature]] the [[Electrical Current|current]] increases rapidly with the [[Potential Difference|potential difference]]
*At a low [[temperature]] the [[Electrical Current|current]] increases slowly with the [[Potential Difference|potential difference]].
 
====Explanation====
: The [[Electrical Resistance|resistance]] of an 'NTC' [[thermistor]] increases as the [[temperature]] decreases.
