Streetlights, emergency lights,and security lights must automaticallyturn on when it gets dark. You basethe control circuit on the resistance of aphotoresistor or another LDR (light-dependentresistor) ...

This is a very interesting a.c. voltage stabilizer that uses a LDR or photoresistor to stabilize an alternating current (AC). If the voltage increases then the brightness of the light bulb increases ...

Resistors are one of the fundamental components used in electronic circuits. They do one thing: resist the flow of electrical current. There is more than one way to skin a cat, and there is more than ...
