An electric car has an electric motor. The energy stored in the car's batteries is converted into the rotation of the wheels.
A food processor works on exactly the same principle. Electrical energy from the outlet is turned into rotation in the food processor, and if you attach blades to the part that turns, it can cut up your food.
Light bulbs (AC)- When you turn on a light bulb, electricity flows through the filament. As the filament heats up it produces light.
Back up home generator (DC)-A dc generator is an electrical machine which converts mechanical energy into direct current electricity. This energy conversion is based on the principle of production of dynamically induced emf.
