1. An electric iron consists of coil of high resistance covered by mica sheets and kept inside heavy metal block.
2. When electric current passes through the coil it gets heated and can be used for ironing.
3. The mica sheet is a bad conductor of electricity and good conductor of heat. It prevents the current from entering into the metal and thus protects the user from getting an electric shock.
