Answer 1

$\huge{Answer:-}$

$<b>$

Mica is used in electric appliances and in electric iron as it has good magnetic properties as well as great di-electric factor.

Moreover, it too has low power loss factor and thus used in electric appliances.

But it is used as electric iron as it has considerable amount of resistance and resistivity so as to produce heat. Thus Mica is used in electric irons.

Answer 2

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

Mica is used in an electric iron because it is bad conductor of electricity and good conductor of heat.

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

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.

Hope it helps!
