Electrical and Electronics Engineering is all about electricity. Electricity has some fundamental properties associated with it. This magnitude of these properties is expressed in terms of quantities and their units. Given below is a list of these quantities, their symbols, units, and abbreviations.
While majority of derived units are takes from SI system, unit for energy is kWh instead of joule. Since kWh is more popular in Electrical Engineering.
