How the electrical appliances work using the heating effect of electric current?

When large electric current flow through a circuit and hence through fuse wire, a large amount of heat production occurs. Due to this large heat production, the fuse wire melts and the circuit breaks so that the current stops flowing through the circuit. This saves the electric circuit from burning.

How the electrical appliances work using the heating effect of electric current Class 7?

When an electric current is passed through a high resistance wire (like nichrome wire), the resistance wire becomes hot and produces heat. This is called the heating effect of current. When an electric current passes through a high resistance wire, the electric energy gets converted into heat energy.

Which appliance works on heating effect of electric current?

The devices which work on this property of heating effect are electric heater, electric iron, electric fuse, etc. In an electric heater and an electric iron, we have coils of the conducting materials which has the property of producing heat when electric current is passed through them.

How does the heating effect of electric current work?

When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called heating effect of current.

How is heating effect of electric current used in electric bulb?

The heating effect of electric current is used in the following applications: Electric Bulb: In an electric bulb, the filament of bulb gives light because of heating effect of electricity. … In the case of flow of higher voltage than specified, fuse wire melts and protects the electric appliances.

What is heating effect of electric current give an example?

This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called the heating effect of current. Example, Electric iron, electric toaster, water heaters, etc., work on this effect.

What is heating effect of electric current 12?

Hint: Heating effect of electric current is observed when the current passes through a coil with high resistance, this resistance converts the electrical energy into heat energy. The devices which utilize this heating effect of electric current are generally made from high resistance wires/ plates or coils.

What is heating effect of electric current give two examples?

(1)Electric Bulb: The filament of the bulb is made of tungsten. It gives light due to the heating effect of the electric current. (2)Electric iron: It is made of alloys. Alloys have high melting point.

Which two devices work on the heating effect of current?

The two devices that work on the heating effect of electric current are a bulb and an electric fuse.

Which of the following appliances doesn’t work on heating effect of current?

The correct answer is the Microwave.

What is the effect of electric current?

When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects. The main effects are heating, chemical and magnetic effects. …
