Question

Give one example each of the transformation of electrical energy into heat, light and mechanical energy and one example of the transformation of kinetic energy into electrical energy.

Answer 1

Dear Student ,

1. A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electric charges into heat (thermal energy) in the filaments that turn red hot to cook your toast.
2.The electric current moves from the wall outlet into the light bulb in the lamp supplying electrical energy. When the electric charges slow down in the filament to light the light bulb, light energy is created.
3.A blender transforms electrical energy into mechanical energy.
4.
​​​​​The process begins by having the wind's kinetic energy convert to mechanical energy by spinning a wind turbine. The mechanical energy in the wind turbine is then transferred to an electrical generator, where the mechanical energy is transformed into electrical energy.
