FAQs on Applications of Heating Effect of Electric Current Video Lecture - Science Class 7

1. What is the heating effect of electric current?
Ans. The heating effect of electric current refers to the production of heat when an electric current flows through a conductor. This effect occurs due to the resistance offered by the conductor to the flow of electric current.
2. How does the heating effect of electric current work?
Ans. The heating effect of electric current occurs due to the conversion of electrical energy into heat energy. When current flows through a conductor, the electrons collide with the atoms of the conductor, causing them to vibrate and generate heat.
3. What are some applications of the heating effect of electric current?
Ans. The heating effect of electric current finds various applications in our daily lives. Some common applications include electric heaters, electric stoves, electric irons, electric toasters, and electric kettles, where the heating effect is utilized to generate heat for cooking, heating, and other purposes.
4. How is the heating effect of electric current utilized in electric heaters?
Ans. Electric heaters utilize the heating effect of electric current to produce heat. Electric current passes through a heating element, usually made of a high-resistance material, such as nichrome wire. The resistance of the wire causes it to heat up, and this heat is then transferred to the surrounding air, warming up the room.
5. Is the heating effect of electric current dangerous?
Ans. The heating effect of electric current can be dangerous if not handled properly. Excessive heat generated due to high current flow can lead to fire hazards. It is important to use appropriate wiring, fuses, and circuit breakers to prevent overheating and ensure electrical safety.
