To measure phase angle on a scope, connect the two inputs to the two sources, trigger off of one, and watch both. Measure the period of one and compare crossover difference with the other as a percentage of the period of the first, times 360 degrees.
Make sure the peak to peak offset for both inputs is equal, otherwise the crossover voltage won't be right.
Note that the period is 100% and is equivalent to 360 degrees. One way to make the calculation easier is to adjust the horizontal calibration so the first input has a period equal to 36 minor divisions - each division will equal 10 degrees in this case.
Also note, if you are comparing voltage and current, that your polarity is correct. This can be an issue if you are measuring across a small series resistor - the high side is voltage and the high to low side differential is current - but it is inverted.

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.
How you measure power factor in three phase load by two wattmeter method?
First of all, you can only measure power factor of a three-phase load, provided that it is balanced load. The power factor can then be found by determining the cosine of the phase angle, using the following equation:tan (phase angle) = 1.732 ((P2-P1)/(P2+P1))...where P1 and P2 are the readings of the two wattmeters.
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
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.

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).
Explain what the measure of an angle is?
the measure of an angle is the degrees of an angle.
How do you measure a angle?
you can measure a angle with a protracte.
What is the relationship between the measure of an angle and the reflex measure of the angle?
they both measure the angle in degrees
The measure of an acute angle is half the measure of an obtuse angle.What is the measure of an obtuse angle?
The measure of the obtuse angle would then be double that of the acute angle.
What is the measure of the supplementary angle of an interior angle?
The measure of the exterior angle.
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 rifle scope MOA?
MOA is the abbreviation for "minute of angle". It is a measure of angle at a given distance. 1 MOA equals 1 inch at 100 yards. A scope that is 1/4 MOA would move the bullet impact 1/4 inch per click of adjustment at 100 yards.
How do you calculate 3 phase kWh of wye connection measuring amps on each phase?
For a balanced load, you don't have to worry about phase values when you want to determine the power (or, in this case, the energy), whether delta or wye. Rather, you always use line values:P = 1.732 VL IL cos (phase angle)For an unbalanced load, however, you need to measure the phase voltage and phase current and power factor for each of the three phases, and add them together:P = [VpIp cos (phase angle)]phase A +[VpIpcos (phase angle)]phase B+[VpIp cos (phase angle)]phase CTo then calculate the energy expended in kilowatt hours, you need to multiply the total power (as calculated above), expressed in kilowatts, by the time for which the load is operating, expressed in hours.
Find the measure of angle and if the measure of angle abc60 the measure of angle and is represented by 5x 7 and the measure of angle dbc is represented by 9x-3?
