Question

A photoelectric cell is a device which:(a) converts light into electricity(b) converts electricity into light(c) stores light(d) stores electricity

Answer 1

converts light energy into electrical energy option (A)

Answer 2

The correct answer to this question is option a: converts light into electricity.

• The options given here are the principles on which different electrical devices work.
• Photoelectric cell as the name says uses photon energy or light energy and converts this energy into electric energy.
• This type of effect is known as the photovoltaic effect.
• The amount of electricity produced is dependent on the amount of light that strikes the cell surface.
• Because of its dependency on light to produce electricity, it is also called a light-dependent cell.
• For example, Solar cells.
• It does not store light or electricity.
• Hence, option a is the correct principle for the photoelectric cell.
