We often see the peak and trough (maximum positive and maximum negative excursions) of the sine wave considered as points of momentarily constant voltage. Those points are at phase angles of 90 degrees and at 270 degrees.

What is the phase angle between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
Why phase angle is zero when voltage and current are in phase?
1 & 3
What is the power factor when the current and voltage are in phase?
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).

In a purely resistive ac circuit the current and voltage?
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.
What is Vector meter?
A vector impedance meter is used to measure impedance and phase angle, this is done by calculating voltage and current through an impedance and then calculating Z and phase angle with that, now there are two modes for operation i.e constant current mode and constant voltage mode.CONSTANT CURRENT MODERead more: What_is_vector_impedance_meter_explain_with_circuit_diagram
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 between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
What is the phase voltage inside a motor if one phase is lost and what is the voltage between the other two phases?
The phase voltage is usually constant and determined by the supply voltage.
Why phase angle is zero when voltage and current are in phase?

At what condition the phase angle equal zero?
That means that the voltage and the current are in phase.
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.
Do you expect angle in rlc series circuit to be a constant?
The phase shift angle of an RLC circuit is constant for a constant frequency, but changes with different frequencies.The phase angle of the AC in the RLC circuit is however continuously changing. Otherwise it wouldn't be AC.
What is the power factor of an resititive load?
Power factor is the cosine of the phase angle between voltage and current. In a resistive load, current is in phase, i.e. with a phase angle of 0 degrees, with respect to voltage. Cosine (0) is 1.
When modulating freq is doubled then modulating index is halved and modulating voltage remains constant system is?
It's Angle modulated system where the amplitude remains constant & frequency & phase varies with respect to modulating signal.
What is the power factor when the current and voltage are in phase?
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).
How capacitor and resitor in a circuit effect the phase of input voltage?
A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.
