Question

Name a device which converts mechanical energy into electrical energy. Explain the underlying
principle and working of this device with the help of a labelled diagram.​

Answer 1

Answer:

The correct answer is - Electric generator.

An electric generator is a device which converts mechanical energy into electrical energy.

A generator converts mechanical energy into electrical energy, while a motor converts electrical energy into mechanical energy. Both the devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.

The modern-day generator works on the principle of electromagnetic induction discovered by Michael Faraday in 1831-32. Faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.

A generator forces electrons to flow through an external electrical circuit. It is somewhat analogous to a water pump, which creates a flow of water but does not create the water inside.
