1. A switch is a device that is used for making and breaking electric current in a circuit. It is used to turn on and turn off daily used equipment like television, washing machine, fan, light, etc.
2. Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
3. A wire is a flexible strand of metal, usually cylindrical. Wires are used for establishing electrical conductivity between two devices of an electrical circuit. They possess negligible resistance to the passage of current.
4. The definition of a bulb is any plant that stores its complete life cycle in an underground storage structure. The primary function of these underground storage structures is to store nutrient reserves to ensure the plants' survival.
