Answer:
Explanation:
light switches behave like normal switches but instead of working with involvement of external force light switches have a sensor (light sensor). there are different light sensors depending on their principle of working we use it in different applications.
one type of them is when light falls on sensor, it will start conduction of small electric current and amplifier circuit senses the current and turns off/ON the light depending on the configuration of amplifier.
