Electric iron contains a resistance wire (nichrome) . When a current of I amp is passed through the wire, electrical energy equal to I^2Rt (joules) is produced which is entirely converted to heat. This is a unique characteristic of resistance element as compared to capacitors or inductors where there is no power dissipation. Here R = resistance of the wire in ohms and t= the amount of time that the current passes through the resistance wire. The metal base at the bottom of the electric iron is thus heated up.

An electric flat iron is a type of clothes iron that runs on electricity. The first electric flat iron was invented by Henry W. Seely.

Steel & Iron conduct electricity, but have high resistance. They make good heating elements.

Iron is used in electricity in many different ways. For example, it is used in fuel cells by using an iron-based molecule. This in turn makes them more economical.
Wires are used as electricity conductors.
The Earth's outer core produces electricity caused by abundance of iron. The Earth rotates and as it does that the iron generates high electric currents that then produce electricity. That also can generate magnetic fields.
To determine the number of watts of electric energy consumed by electric iron, we need to multiply the volts and the ampere used by that particular electric iron, so the product of those two is the watts used by the electric iron.
