Question

State energy changes in ceiling fan while in use?

Answer 1

Hint:We provide electrical energy to the ceiling through our domestic electricity which makes the fan rotate. The rotatory motion of blades is a mechanical process.

Complete step by step answer:
There is conversion of electrical energy into mechanical energy in a working ceiling fan. There is also conversion of both electrical and mechanical energy into heat energy due to resistance of the electrical component and friction between mechanical components. The ceiling fan has an electric AC motor that converts electrical energy into mechanical energy.
First, the capacitor of the ceiling fan generates torque in the electric motor, causing it to start and run. As the electric current reaches the motor, it enters coils (copper windings) of wire that are wrapped around a metal base (soft iron core). When this current passes through the wire, it creates a magnetic field which further creates a couple in a clockwise motion. In this way, the electric energy is being converted into mechanical energy and causes the motor coils to spin. The blades attached to the motor also start rotating with the spinning of the coils.

Note: What is the difference between electrical energy and mechanical energy?
There is no big difference between them. Both of them are a form of energy and energy keeps changing its form. The only difference is how they are being produced.There are only two kinds of energies in this universe: Potential energy and Kinetic energy, everything else is just a manifestation of these 2 forms. The sum of these two energies is often called mechanical energy of the system and electrical energy also possesses both in form of electric potential and kinetic energy of electrons.
