Q = it, where Q is the amount of electricity flowing through the cross section, I is the current intensity in the circuit, T is the time required to flow through these amounts of electricity Q, and I is numerically equal to the amount of electricity flowing through the cross section per unit time.

Charge amount formula:

(1)Q=It (where I is current, unit a, t is time, unit s).

(2)Q=ne (where n is an integer, e refers to charge, and e =1.602176634×10 (-19) coulombs, generally taking the first two decimal places).

(3)Q=CU (where c refers to capacitance and u refers to voltage)

Electricity calculation rules:

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. The calculation rules are as follows:

A, high voltage meter users:

Forward reactive power+| reverse reactive power |

These include:

Forward reactive power = (this month's table-last month's table) * multiplication

Reverse reactive power = (table words of this month-table words of last month) * multiplication

Second, the high voltage and low meter users:

Forward reactive power+| Reverse reactive power-reactive copper loss-reactive iron loss |

That is, the sum of the absolute values of the difference between positive and negative reactive power (reactive copper loss+reactive iron loss).
