Electric Current and its Effects

This topic lists the different symbols of electric circuit components. We will also learn their uses in an electric circuit.

In this topic, we will learn that the heating effect of electric current involves the conversion of electrical energy into heat energy. The magnitude of current and resistance of a wire generate heat in the wire. This effect can be seen in electric bulbs.

In this topic, the magnetic effect of electric current is explained with the help an activity. Wire behaves like a magnet when an electric current passes through it.

This topic explains the concept of electromagnet with examples. When a coil of an insulated wire is wrapped around a piece of iron, it can carry current and is called an electromagnet. Electromagnets are used in many devices.

This topic discusses the use of electromagnet in electric bell. Electric bell has an electromagnet in it. It consists of a coil of wire wound on an iron piece. This coil acts as an electromagnet.
