What is meant by the phase angle in an alternating current circuit?
In electronics, phase angle refers to the number of electrical degrees of lag or lead between the voltage and current waveforms in an ac circuit.
What is a phase angle in electricity?
phase relations. • A Phase relation, or phase angle, is the angular difference between. sine waves of the same frequency. • Phase angle is the portion of a cycle that has elapsed since another. wave passed through a given value.
What is the difference between angle and phase?
Definition: The phase difference between the two electrical quantities is defined as the angular phase difference between the maximum possible value of the two alternating quantities having the same frequency. The angle between zero points of two alternating quantities is called angle of phase differences.
What is the phase relationship between voltage and current?
Draw a phasor diagram showing the phase relationship between current and applied voltage. 1. Inductive reactance of the coil X L = 2 · 3.14 · 60 · 0.4 2. Current through the circuit I = 115 / 150.7 3. Draw a phasor diagram showing the phase relationship between current and applied voltage
How is THD of line currents related to firing angle?
The THD of line currents depends not only on the rms value of the reinjection current but also on the angle of this current. Angle of reinjection current plays a very important rule with the value of THD of the line current of the three-phase SCR converter. The best angle for reinjection current has been derived for different firing angle (α).
The current phasor lags the voltage phasor by the angle, Φ, as the two phasors rotate in an anticlockwise direction as stated earlier, therefore the angle, Φ is also measured in the same anticlockwise direction.
How to find the phase of an inductive circuit?
A 0.4 H coil with negligible resistance is connected to a 115V, 60 Hz power source (see Figure 2 ). Find the inductive reactance of the coil and the current through the circuit. Draw a phasor diagram showing the phase relationship between current and applied voltage.
