Question

Pick out the suitable appliances to conserve the electric energy.
(Florescent bulbs, copper choke, solar water heater, electric water heater, tungsten bulbs, electric choke)

Answer 1

The appliances used to conserve the electric energy are Fluorescent bulb, Solar water heater, electric choke. These appliances use comparably lesser electrical power.

Fluorescent bulb a glass tube which radiates light when phosphor on its inside surface is made to fluoresce by ultraviolet radiation from mercury vapour.

Solar water heater is a device which uses the principle of the conversion of sunlight into heat for water heating using a solar thermal collector.

An electrica choke is an inductor used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC).
