Answer» What are the different uses of electricity? People USE electricity for lighting, heating, cooling, and refrigeration and for operating APPLIANCES, computers, electronics, machinery, and public transportation systems. Write the the difference between primary cell and secondary? A primary cell cannot be recharged whereas a secondary cell can be recharged. In a primary cell chemical reaction is irreversible whereas in a secondary cell chemical reaction is REVERSIBLE. A primary cell is light and LESS expensive whereas a secondary cell is heavy and expensive. What is the function of electric switch? The purpose of a switch in a series circuit is to make it easy to open or close the electrical circuit, turning the flow of electricity on or off.
