Detailed Solution
Download Solution PDF- Mica is a good insulator of both electricity as well as heat and can withstand high temperatures.
- It is also transparent.
- These properties were found suitable to use mica as an insulating material in an electric iron.
- Plastic, rubber & silica do not have the above-mentioned properties.
- Mica electrically insulates the filament from the body of the iron, which can become accidentally live if there is a breakdown of insulation.
- Mica transmits the heat from the filament to the front plate of the iron. At this point, it is worth mentioning here that the heat is transmitted by radiation and not by conduction.
- Radiation follows the laws of optics. Though mica is a thermal insulator, it permits transmission of heat through radiation on account of it being transparent.
