Peering Into the Electric Eye: What is a Photoresistor?
This activity aims to introduce to students a photoresistor, which is often used in a light dependent voltage divider circuit. A photoresistor is part of a larger family of devices or sensors known as photodetectors. A photodetector’s resistance to electrical current changes when it is exposed to light.
