Resistors, used to control and limit current, Resistor preferred values, selecting the nearest value from the E24 series, Resistor tolerance, shows how much above or below the stated value of the resistor might be, Resistor power rating, gives the limit of how much power can be dissipated safely by the resistor, Resistor colour codes, four coloured bands on the resistors body, Total resistance in series, equals the sum of all resistor values, Total resistance of two equal resistors connected in parallel, equals half of their individual values, Potentiometer, can be used as a variable resistor or voltage divider, LDR, A resistor that changes its resistance with a change of light, Thermistor, A resistor that changes its resistance with a change of temperature, LEDs, must be connected in series with a protective resistor, A light or heat sensing circuit, has the sensor at the top, A dark or cold sensing circuit, has the sensor at the bottom, Reed switch, uses magnetism to open or close the circuit
