LIGHT DEPENDENT RESISTORS Technology Student PDF FILE CLICK HERE FOR PRINTABLE WORKSHEET BASED ON WORK BELOW: LDRs or Light Dependent Resistors are very useful especially in light dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 1000 000 ohms, but when they are illuminated with light resistance drops dramatically. LED circuit In electronics, an LED circuit or LED driver is an electrical circuit used to power a light emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. Resistor A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.High power resistors that can dissipate many watts of electrical power as heat, may be used as ...
