Question

Describe photoelelctric effect as a source of electricity

Answer 1

The photoelectric effect is a phenomenon in physics. The effect is based on the idea that electromagnetic radiation is made of a series of particles called photons. When a photon hits an electron on a metal surface, the electron can be emitted. The emitted electrons are called photoelectrons.

Answer 2

so photoelectric effect was given by einstein. He explained photoelectric effect. It basically when the light rays falls on a metal and electron on the last shells gets energised which results in moving out of electron. When a circuit is connected with this metal it acts as a battery and we can see motion of current. But only minute amount of current can be given as electrons move at a slow rate.
