low power

Generally speaking, the electrical energy consumption of low-power electronics circuits is measured in watt.hours (W.h) whereas the energy consumption of household appliances and most other pieces of equipment, apparatus or machinery that take more power than items which only have low-power electronics circuits in them is measured in kilowatt.hours. (kW.h)

in digital electronics, engineers use low voltages like 5 or 12 or 24 volts but when they want to transfer electrical energy in high power which means high voltage and high ampere they use power electronics .

in power electronics sometimes the transistor or diode or in power electronics language IGBT and thyristor can work in 10000 volt or higher voltages

Electronics are used in thermal power plants when the power from the thermal power plants are transferred to a storage source. There, electronics comes in.
