Description:
This quiz is based on Electric Current and Its Effects. Electric current is the flow of electric charge through a conductor. It is produced by electric cells and batteries and flows only in a closed circuit. When electric current passes through a wire, it produces different effects such as heating and magnetic effects. The heating effect is used in devices like electric bulbs, heaters, and irons, while the magnetic effect is used in electromagnets, electric bells, and motors. Safety devices like fuses are used to protect electrical appliances from damage due to excess current.
