How do street lights go on?
In a modern streetlight, a small circuit replaces the bird and turns the light on when the amount of light falls below a certain threshold. If a small amount of current flows from emitter to base, then a large amount of current can flow from emitter to collector.
Why are LDRS used in street lights?
Streetlights have potential divider circuits that cause the light to come on automatically at nightfall. When it is dark, the resistance of the light-dependent resistor (LDR) (R 2) is high, which means that the output voltage is high and can be used to switch on the light.
