WebTesting Components. The GCSE examination will require an understanding of the variation of resistance in the following devices: Filament lamps. Diodes. Thermistors. LDRs. Luckily, the design and use of the circuits to investigate how resistance varies is broadly similar for each component. WebApr 24, 2024 · All materials have resistance, and to some degree, that resistance varies with temperature for all materials. In a conductor or conventional resistor, this variation is negligible, but in a thermistor, a single degree change in temperature can produce a resistance change of 100 ohms or more.

WebDec 29, 2024 · Thermistors are used for HVAC functions and vital applications like emissions control and process controls. The thermistor can also be found functioning in monitoring and maintaining engine temperature. The military uses thermistors within military vehicles, including trucks and tanks. WebANSWER: A. The resistance of the thermistor increases as the temperature decreases. Since the thermistor and resistor R are connected in series, the current I in both of them is the same. Ohm’s law states that V = IR. Since the resistance of the thermistor increases, and I is the same, the potential difference V across it increases. state bank of india lone
