Question

Why is Mica used in Electric Iron?

Answer 1

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 for use in electric iron. ... It transmits the heat from the filament to the front plate of the iron

Answer 2

$\large\boxed{\fcolorbox{blue}{yellow} {Answer}}$

1. Mica is a bad conductor of electricity and good conductor of heat.

2. In an electric iron, the coil of high resistance is kept between mica sheets so that there is no electrical contact between the coil and the heavy metal block of the iron through there is heat transfer.

This protects the user from getting an electric shock.
