How light produces electricity in a photocell
WebA photocell's working theory will depend on the phenomenon of electrical resistance & the photoelectric effect. This can be used to transform electrical energy into light energy. The positive (+ve) terminal of a battery is connected while the emitter terminal is connected to the negative (-ve) terminal & collector terminal. WebThe photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons.It is important to note that the …
