Words and meanings to learn
thermistor
A type of resistor whose resistance decreases as temperature increases (NTC type) or increases as temperature increases (PTC type); used in temperature sensors and controlling devices like fans or ovens.
resistance
A measure of how much a component opposes the flow of electric current, measured in ohms (Ω).
control variable
The variable(s) kept constant in an experiment to ensure a fair test
LDR (light dependant resistor)
A type of resistor whose resistance decreases as the light intensity falling on it increases; used in devices such as street lights, cameras, and security systems.
fixed resistor
A resistor with a set resistance value that does not change with conditions like temperature or light; used to limit current in a circuit.
