Electric current is the flow of electric charge through a conductor. It is measured in amperes using an ammeter. When current flows through a conductor, it produces several effects. The heating effect occurs when electrical energy is converted into heat energy, which is used in devices like electric heaters, irons, and bulbs. The magnetic effect of current means that a current-carrying conductor behaves like a magnet, which is the principle behind electromagnets, electric bells, and motors. This Electric Current and Its Effects Class 8 MCQ explores these phenomena and their technological applications comprehensively. The chemical effect occurs when current passes through a liquid conductor, causing chemical reactions, a process called electrolysis used in electroplating. Understanding electric current and its effects helps students learn about electricity, electrical devices, and their applications in technology and industry. Attempt these 10 multiple-choice questions to assess your understanding of electric current and its various effects.
