Question

write the name of heating appliances which do not use heating coils​

Answer 1

Explanation:

Nichrome

Nichrome is nothing but an alloy of Nickel and chromium. It has a special characteristics that it has high boiling point as well as melting point and high resistance. Due to this reason it is used as a heating coil in electrical heating devices , more the resistance in a wire mode is the heat produced.

Answer 2

An induction Cooker is a heating appliance that does not use heating coils​.

• The induction cooker consists of a copper wire placed underneath the ceramic plate on which the vessel is kept.

• An induction cooker transfers electrical energy by the process of induction from a coil of wire into a metal vessel.
• A high frequency of the alternating current is passed through the coil. which produces a magnetic field.
• This magnetic field induces an electric current in the plate, known as Eddy Current. The current flowing in the plate produces resistive heat which in turn, heats the food
