What is electric current and its effect?

Lighting effect of electric current is used in bulbs, fluorescent tubes. … Electric bell works based on the principle of magnetic effect of electricity. Electromagnet. Wrap a wire around a soft iron piece (known as the core). When an electric current is passed through the wire, the iron piece behaves like a magnet.

Why alloys are used in electrical heating devices?

As we know alloys have high resistivity and high melting point as compared to pure metals. … So alloys cannot easily burn or oxidize at higher temperature. Now as we want higher temperature in heating devices so we use alloys in heating devices.

What is heating effect of electric current name three devices that work on his effect?

Three appliances which uses the ‘heating effect of current’ are light bulb, electric toaster and electric iron. Explanation: When a current flows through a conductor it produces heat in it.
