Heater is a commonly used electric heating device. People can't live without it.
working principle
For example, the electric heater uses metal to generate eddy current in the alternating magnetic field to make itself heat and absorb, which is the conversion of electric energy into light energy; For example, solar water heaters can absorb solar radiation heat energy and convert solar energy (photoelectric effect) into heat energy at the same time; Bioenergy is a kind of energy that stores solar energy in the form of chemical energy with biology as the carrier. It directly or indirectly comes from photosynthesis of plants. In addition, there are such energy conversion modes as nuclear energy and wind energy, but they generally need to be converted into electric energy for use.
