GCSE THERMISTOR ISA METHODS
GCSE Science Core Practicals: Thermistors ISA Method
This is a method for the Thermistors ISA in the AQA GCSE Additional Science and GCSE Physics courses. Hypothesis. The higher the temperature the lower the resistance of the thermistor. This is because as the thermistor is heated more electrons gain enough energy to move into the conduction band and act like free electrons.

Science GCSE ISA Methods: Thermistors - Additional Science
Method Connect the thermistor to the multimeter. The multimeter is set to work as an ohmeter, measuring resistance directly. Set the scale to an appropriate range setting. Fill the beaker with ice and place the thermometer into it. Place the thermistor in the beaker so that it is totally submerged in the ice.Author: Scienceman
GCSE PHYSICS - Electricty - What is a Thermistor? - What
What is a Thermistor used for? A thermistor can be used in a circuit to detect a temperature change. For example, a thermistor may be used to keep a freezer at the right temperature. A circuit with a thermistor in it can switch the freezer on if the temperature gets too high and switch the freezer off again when the correct low temperature is reached.

Mar 18, 2014In GCSE we deal only with NTC thermistors so as u told the resistance decrease gradually when the temperature increase. So ull get a gradual decreasing curve when resistance is plotted against temperature. In this experiment use temperature as the independent variable. As u need to increase the temp..

Temperature is the only factor that affects the resistance of a thermistor. The idea of it is that the resistance decreases as temperature increases. Thanks to all of those who replyed. Ive now done my isa paper 1 and I'm gonna do paper two on Tuesday. It was reaalllly easy thank god,..
GCSE Additional Science GCSE Physics ISA Light dependent
GCSE Additional Science GCSE Physics ISA Light dependent resistors LDRs. As the intensity of light falling on a beaker increases, the resistance of the LDR decreases. Connect up the LDR to the multimeter. The multimeter should be set to measure resistance. Place the bench lamp so that it is 1m away from the LDR (use the metre rule to measure [PDF]

1. Use the kettle to boil water and then put 200 ml ofthis hot water into a 250 ml beaker. 2. Use a piece of cardboard, with a hole for the thermometer, as a lid for the beaker. 3. Insert the thermometer through the hole in the cardboard lid so that its bulb is in the hot water.
