See more A resistor restricts or limits the flow of electrical current. A fixed resistorhas a resistancethat does not change. See more The resistance of a thermistor depends on its temperature. At low temperatures, the thermistor has a high resistance. As the temperature increases, the resistance decreases. A thermistorcan be used in thermostats or heat … See more Moving the position of the slider on this resistor, changes the resistance. A variable resistoris used in some dimmer switches and volume controls. See more The resistance of a LDR depends on light intensity. At low light levels, the LDR has a high resistance. As the light intensity increases, the resistance decreases. A LDRcan be used as a sensor in cameras or automatic lights … See more WebThe more resistance there is in a circuit, the less current will flow. Find out more with BBC Bitesize.
