In a photocell, light energy is converted into

(A) potential energy
(B) chemical energy
(C) heat energy
(D) electrical energy

Correct Answer : electrical energy
Explanation : Photocells are scientifically known as Photoresistors. A photoresistor is made of high resistance semi-conductor. If light falling on the device is of high enough frequency, photons absorbed by the semiconductor given bound electrons enough energy to jump into the conduction band. The resulting full electron conduct electricity, thereby, lowering resistance, photo-resistors are basically photocells.
