Question

What are the applications of heating effects of electric current?

Answer 1

Hint:Electric current heating impact commonly employed in our daily lives. Electric irons, kettles, toasters, heaters, and other appliances are utilized as replacements to traditional cooking and laundry processes. Electric bulbs, which are an alternative to the current lighting, use the same technology. Over the years, these devices have altered the world. In this section, we will look at the notion of electric current heating and its applications.

Complete step-by-step solution:
Applications of heating effect of electric current:
Electric Iron: Mica is an insulator used in irons that is inserted between the metal component and the coil. The passage of current heats the wire, which is then transferred to the metallic part via mica. Finally, the metal component is heated and utilized for ironing garments.
Electric Bulb: An electric bulb constructed out of a thick metallic wire made of tungsten metal. The metal is preserved in an inert atmosphere by utilizing a neutral gas or a vacuum. When a current passes through a tungsten wire, it heats up and generates light. The majority of the electric power drawn in the circuit from the electrical source dissipated as heat, with the remainder radiated as light energy.
Electric Heater: As a coil in an electric heater, high resistance nichrome wire is employed. The wire coiled around grooves made of ceramic or China clay. When current travels through the wire, it heats up, which is then utilized to heat cooking containers.
Electric Fuse: An electric fuse is a safety device used to limit current in an electric circuit that melts and breaks the connection if there is an excessive current flow through the circuit. It aims to protect the circuit and the appliances connected to it from damage if the current exceeds the fuse's limit due to voltage fluctuations or loose connections.
Electric kettles: The heating element is located at the bottom of the kettle, where the liquid being heated covers it. The heat is subsequently absorbed by water and convectively spread throughout the entire solution.
Electric cookers: When turned on, electric cookers become red hot, and the heat energy produced is absorbed by the cooking pot via conduction.

Note:The following are the drawbacks of the current heating effect:
A portion of the electric current that travels through the conductor is transformed into heat energy. It is a waste of energy.
The heat generated can damage the insulation and other electrical components or possibly start a fire.
It reduces the life of various circuit components.
Due to counteracting the heating impact, an additional cooling system must add to the circuit. It raises the price.
