The primary purpose of a fuse in an electric circuit is to protect circuits and appliances by stopping the flow of any unduly high electric current. It acts as a safety device. If a current larger than the specified value ...

In an electric bulb, most of the power consumed by the filament appears as heat, but a small part is radiated as light. The primary form of energy conversion is from electrical energy to heat, with measures such as using ...

In an electric bulb, the filament must retain as much of the heat generated as possible to get very hot and emit light. Tungsten, a strong metal with a high melting point (3380°C), is commonly used for making bulb filaments. ...

Electric laundry irons, electric toasters, electric ovens, electric kettles, and electric heaters are examples of familiar devices that utilize Joule’s heating for their operation.

The heating effect of electric current is harnessed in devices such as electric laundry irons, toasters, ovens, kettles, and heaters. These devices operate based on Joule’s heating, converting electrical energy into heat for specific applications.
