1. Heating Element: A heating element is a component used in various devices to generate heat. It’s typically made of a material with high electrical resistance, such as nichrome wire. When an electric current passes through the heating element, it encounters resistance, which causes the wire to heat up. This heat is then transferred to the surrounding environment, serving purposes like heating water in electric kettles, generating warmth in space heaters, or baking in ovens.
  2. Transformer: A transformer is an electrical device that is used to change the voltage of an alternating current (AC) electrical signal. It consists of two or more coils of wire (called windings) that are wound around a core. The primary winding is connected to the input voltage source, while the secondary winding is connected to the output load. Transformers are commonly used to step up or step down voltages, depending on the number of turns in the primary and secondary windings.
  3. The heating element of the transformer increase the resistance with age. Heating element transformers are multi taps transformers to compensate for this change of resistance.
