What is the difference between phase angle and phase difference?

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 difference between frequency modulation and phase modulation?

The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.


What affect the phase angle?

Apparent power is the vector sum of a load's true power and its reactive power. If you draw a 'power diagram', the phase angle will be the angle between the true power and the apparent power. If true power is fixed, then increasing the phase angle will result in a greater value of apparent power.


What will be the resultant voltage if the two phase voltage having no phase difference?

If two phase voltages are the same voltage and the same phase angle, the the resultant voltage will be twice the voltage.


What is the phase angle difference between inductive load and resistive load?

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.


What is the phase difference of RC circuits?

If you understand complex numbers then you will see that the imaginary value jXC which depends upon the value of C,capacitance, determines the value of the phase displacement angle.Answer">AnswerYou don't need to understand complex numbers to understand this topic. The term you are looking for is 'phase angle', not 'phase difference'. This is defined as the angle by which the load current leads or lags the supply voltage. For a resistive-capactive circuit, the load current leads the supply voltage and, so, the phase angle is leading. The actual angle depends on the values of R and XC (capacitive reactance). Incidentally, the 'displacement angle' is something different again!


How do you convert j equations to phase angle equation?

The phase angle is the angle that has a tangent of (imaginary part)/(real part).


Why do you rate a dc machine in watt but a transformer in kilo volt-ampere?

The difference between watts and volt-amperes is due to the relative phase angle, or power factor, between voltage and current. In a DC system, the two are in phase. In an AC system, with only resistance, the two are also in phase. Add capacitance or inductance and the phase angle changes.


What is phase angle of a resonant circuits?

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.


What is the formula for phase angle?

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.


What is phase angle error of current transformer?

The angle between the expected and actual secondary current is known as phase error.


What will happen to phase angle if the the value of capacitor is increase?

in a series RC circuit phase angle is directly proportional to the capacitance
