Question

why base of an electric iron is made thick and heavy?

Answer 1

Electric iron contains a thick metallic wire made up of tungsten metal. ... When current flows through the tungsten wire, it becomes heated and emits light. Most of the electric power drawn in the circuit from the electricalsource is dissipated in the form of heat and the rest is emitted in the form of light energy.

Answer 2

the thick and heavy base will increase the heat capacity.thus it will be able to absorb large amount of heat energy and its temperature will stay in safe limits,such that the clothes being pressed do not burnt.furthermore,when electric current is switched off,it stays hot for a longer time
