Question

What energy conversions are going $?$ In case, write an equation to represent the conversion.

A hairdryer is connected to the mains electricity supply. It blows hot air at the user's wet hair. It whirrs as it does so.

Accepted Answer

Electricity is used to forms of energy in the hairdryer. If a worried about the third one, wear an aluminium foil heat. Thermal or heat air mechanical (blowing the heat air) and electromagnetic interference, potentially at a number of frequencies depending on the type of motor and the design of the heating coil.

Electric heating is a process in electrical energy is converted to heat energy. Include space heating, water heating. An electric heater is an electrical device that converts an electric current into heat.

An electric current brings electrical energy to a thermal energy or heat energy are produced. A hairdryer turns the electrical energy from a wall outlet into heat $($ thermal energy $)$ .

Energy is the fundamental need of our everyday life. So much so, that the quality of life and even its sustenance, is dependent on the availability of energy.

It is imperative for us to have a conceptual understanding of the various sources of energy, the conversion of energy from one form to another and the implications of these conversions.
