The amount of charge (English) indicates how much charge an object carries.
Generally speaking, the amount of charge is called the electric quantity, which is represented by the symbol Q. The unit is the library (LUN) (symbol C), and the coulomb is the large unit.
The electric quantity of an electron e =1.60 *10-19 library. Experiments show that the charge of any charged particle is either equal to the charge of electrons or protons or an integer multiple of their charge, so the library of1.60 *10-19 is called elementary charge.
Electricity can also refer to the amount of electric energy required by electrical equipment, which is also called electric energy or electric work at this time.
The unit of electric energy is kilowatt hours.
W=P*t(W stands for electric energy; P stands for active power, in kilowatts; T stands for time in hours.
The electricity here is also divided into active electricity and reactive electricity. The unit of reactive power is kilowatt hour (kVar h).
