Hair dryers
The hairdryers hair are now considered an integral part of hair care. In every hair dryer for drying hair, we use an electric current that passes through an electric resistance, which is placed inside it. It is usually in the form of a spiral and is surrounded by a metal lining. This resistance heats up, which means that electrical energy is converted into heat. Heat is transferred from the hotter body to the colder body.
Thus, the air molecules in contact with the resistance heat up. An independent mechanism inside the hair dryer works like a fan and uses an electric motor, which drives a propeller. The rotation of the propeller moves the air, creating a small wind, with the electrical energy being converted into kinetic energy of the air molecules. The movement forces the air in contact with the resistance to move away and the hot air "comes out" from the tip of the dryer. You will find them all at e-dructer.com.
