Electrical circuits- Physics 0.0 / 5 ? PhysicsElectricityGCSEAQA Created by: anxious_student123Created on: 20-09-21 18:40 Switch used to turn a circuit on (closed switch) and off (open switch) 1 of 12 Lamp an electrical current heating a filament so it gives out light 2 of 12 fixed resistor restricts and limits the flow of electrical current. A fixed resistor's current doesn't change 3 of 12 thermistor at low temperature a thermistor has high resistance, when the temperature increases the resistance decreases 4 of 12 LDR (light dependant resistor) the resistance depends on the light intensity (more light, less resistance) used a sensor 5 of 12 Diodes used to convert an alternating current into a direct current 6 of 12 LED (light emitting diode) Emits light when the flow of electric current is allowed 7 of 12 Fuse Designed so when there is too much current it melts and breaks 8 of 12 Ammeter Measures electrical current in Amps 9 of 12 Voltmeter measures the difference between electrical potential 10 of 12 Heater big resistor 11 of 12 Cell the electrical power supply converts chemical energy into electric potential 12 of 12
