The following equation only works for a balanced three-phase load, that is, where each of the three phases is identical in all respects:
P = 1.732 VL IL x power factor, where VL and IL represent line voltage and line current, respectively.
For unbalanced loads, you must determine the power of each phase, using the following equation, and add them together to find the total power:
Pp = VP IP x power factor, where VPand IP represent phase voltage and phase current, respectively.
Power in AC circuit is given as follows,
P = VI*cos(theta)
V = RMS voltage
I = RMS current
cos(theta) = Power factor
Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.

A cold circuit
One possibility for what affects the voltage, is how many light bulbs, motors etc you have in the circuit causing the energy ( voltage ) to be shared.
No. An electrical leak is an electrical ground. When any line grounds out, the circuit breaker will trip and shut the power off. With the power off the watt meter stops recording so that there is no billing at that time.
The load that is connected to the circuit is what draws the power of the electrical circuit.

By definition an electrical circuit is a route or path that starts and finishes at the same place. So there is no part of an electrical circuit that is not necessary, because if there were it would not be an electrical circuit.An electrical circuit needs a power source. Conductors to transmit the voltage from the power source to the load. The final component of the electrical circuit is the load that you want to energize.If you remove any of the components there will be an open circuit and the load will be impossible to operate.
The wire in a circuit helps to pass power to the electrical appliances.
Voltage x current. In a resistor for example it is the voltage drop across it that is relevant, it may be part of a circuit.
An electrical circuit needs Voltage-electrical pressure pushing electrons, and Amprege-electron flow through a conductor. P=IxE (Power= Voltage x Amprege.
To improve the power factor
The watt is a measurement of power. In electrical circuit, to determined watts there is a formula volts x amps = watts
It is the begining of electrial circuit, or where the power comes from, to the end point where it will be used. "Example" circuit breaker panel box has the power, circuit breaker controls the power the cable allows the power to flow to the outlet so when electrical device is plugged in it works.
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
it can blow a circuit
