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.
Q = 3 Vph Iph sin(phase angle) = 31/2 Vline Iline sin(phase angle)

The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
The power factor of a load is the cosine of the angle by which the load current lags or leads the supply voltage. So if they are in phase (phase angle is zero), then the power factor must be unity (1).
The generated angle between phases in a three phase system is 120 degrees.
Q = 3 Vph Iph sin(phase angle) = 31/2 Vline Iline sin(phase angle)
The phase angle is the angle that has a tangent of (imaginary part)/(real part).
Although we use the term 'Phase angle' it's also an angle referred to another phasor (voltage or current).For example,conventionally when expressing power factor, we use 'voltage' as the reference. So the 'phase angle' of a particular phasor is the phase difference between our reference (voltage) & the phasor.As the gist, both mean the same except that 'phase angle' is the direction of the phasor w.r.t. positive x direction (reference)..AnswerBy definition, phase angle is the angle by which a load current leads or lags a supply voltage.Phase difference is the angle between any two electical quantities -for example, the angle two phase voltages of a three-phase system.
what is the formula for a vertical angle
The current through a resonant circuit is (in general) out of phase with the voltage. One measure of the phase angle is this angle. At resonance the phase angel is near zero so it can be used as a parameter to drive a self-tuning mechanism.
The angle between the expected and actual secondary current is known as phase error.
in a series RC circuit phase angle is directly proportional to the capacitance

The phase angle is defined as the angle by which the load current leads or lags the supply voltage.For a purely-resistive load, the phase angle is zero, because the load current is in phase with the supply voltage.For a purely-inductive load, the phase angle is 90 degrees lagging.But few loads are either purely-resistive or purely-inductive; typically, most loads are resistive-inductive. This means that, typically, the phase angle lies somewhere between zero and 90 degrees.
That means that the voltage and the current are in phase.
Your question doesn't really make much sense. Phase angle is simply the angle by which the load current leads or lags the supply voltage.
