Phase applies only to AC current and not DC current. Reactive components - inductors and capacitors - in a system will result in the system output either lagging or leading (capacitance lags and inductance leads).
If we apply an AC signal to the input of a system, we can observe the input and the output on an oscilloscope. If the system lags then the output signal will appear to be shifted to the right relative to the input singal, and vice versa for a system that leads. Since AC signals are periodic we think of one period as being 360 degrees (or 2*pi radians). The phase of output signal relative to the input signal is thus measured in degrees.
For example:
An AC signal of period of 10 seconds and a peak current of 2A is applied to the input of a system. The output is measured and it is found that the output current peaks 3 seconds after the input voltage - so the output lags the input, meaning the circuit has a capacitive reactance. What is the phase of the output relative to the input?
Since T=10 and the phase difference in seconds is 3 the solution is simple:
360 / 10 * 3 = 108 degrees
So; the output lags the input with a phase difference of 108 degrees.
What else can I help you with?
Of cephalic phase or celiac phase or plateau phase or intestinal phase or gastric phase which is not a phase of gastric regulation?
s phase
What is stationary phase and mobile phase?
mobile phase is the phase that consist of the analyte and stationary phase is the phase that is standstill
Why do you have voltage to ground but not voltage phase to phase?
There is phase to phase voltage in 3 phase system.AnswerYou don't get voltage 'phase-to-phase'; it's 'line-to-line'!
What are the three types of phase on its final phase?
single phase, double phase & three phase
What is a part of inter-phase?
g2 phase
What are the game phases in Yu-Gi-Oh?
Game phases? If you mean the phases for a turn in Yu-Gi-Oh then here they are: Draw Phase Standby Phase Main Phase 1 Battle Phase Main Phase 2 End Phase
What does s phase mean?
S-phase (synthesis phase) is the part of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.
What phase is the growth phase?
The other name for the first growth phase is called the G1 phase.
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
What are the key differences between reverse phase and normal phase HPLC techniques?
Reverse phase and normal phase HPLC techniques differ primarily in the polarity of the stationary phase and mobile phase. In reverse phase HPLC, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase HPLC, the stationary phase is polar and the mobile phase is nonpolar. This polarity difference affects the retention and separation of compounds in the sample.
What is the first phase of the cell cycle?
The first phase of the cell cell cycle is interphase, followed by pro-phase, meta-phase, telo-phase, and ending with ana-phase. Enjoy!
What are the differences between reverse phase and normal phase chromatography?
Reverse phase chromatography and normal phase chromatography are two types of chromatographic techniques that differ in the polarity of the stationary phase and mobile phase. In reverse phase chromatography, the stationary phase is nonpolar and the mobile phase is polar, while in normal phase chromatography, the stationary phase is polar and the mobile phase is nonpolar. This polarity difference affects how compounds interact with the stationary phase, leading to differences in separation and elution times.
