What are the characteristics of heating elements used in electric heating devices?

Answer Verified Verified
Hint: A heating element actually converts electrical energy into heat energy through the process of resistive. It is otherwise called Joule heating. Heating elements include an electric current, which is flowing through the coil or ribbon or wire and then it becomes very hot.

Complete step by step answer:
First of all let us get to know about the heating element. The heating elements are made from a coil, ribbon or strip of wire that can produce heat. Heating elements include an electric current, which flows through the coil or ribbon or wire and then it becomes very hot. The element that converts the electrical energy passing through the wire into heat energy is called a heating element. It spawns outward in all possible directions. At first conductors are the best carriers of electricity. In the opposite way insulators are bad carriers of electricity. Both conductors and insulators give resistance to electric currents that flow through them even though in different amounts. Conductors offer a small resistance, while insulators offer a large level of resistance. So, electronic circuits include resistors, which control the amount of current flow. This is how a heating element works. There are many types of heating elements. One of them is metal heating elements. The other one is PTC heating elements. And the last one is composite heating elements. Nichrome is an example for a heating element.

Note:
Convection is the prime method of transfer of heat in fluids such as water and air. It. A fluid like air or a liquid is heated and it travels away from the source, that time it carries the thermal energy along. This kind of heat transfer is called convection.
