How capcitor introduce phase shift?
A capacitor introduces a phase shift in an alternating current (AC) circuit because it does not allow current to change instantaneously. When an AC voltage is applied, the capacitor charges and discharges, causing the current to lead the voltage by 90 degrees in a purely capacitive circuit. This phase difference results from the time it takes for the capacitor to build up and release charge, which affects the relationship between voltage and current in the circuit. Thus, the presence of a capacitor alters the phase relationship between these two electrical quantities.
What is capacitive phase shift?
Capacitive phase shift refers to the delay in the voltage across a capacitor compared to the current flowing through it in an AC circuit. In a capacitive circuit, the current leads the voltage by a phase angle of 90 degrees, meaning that the peak current occurs before the peak voltage. This phase difference results from the capacitor's ability to store and release energy, affecting the overall impedance and behavior of the circuit. Understanding capacitive phase shift is essential for analyzing and designing circuits involving capacitors, especially in applications like filters and oscillators.

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.
How does the phase-shift oscillator get its name?
The phase-shift oscillator gets its name from the phase-shift network used in its design, which introduces a phase shift in the feedback path of the circuit. This phase shift is necessary for maintaining oscillations in the circuit.

A series RC circuit will have a phase shift between 0 and 90 degrees?
If there are only a resistor and a capacitor in the circuit, then the phase shift will indeed be between 0 and 90 degrees. When the resistor and capacitor are in series, the phase shift will be negative when the capacitor is connected to a source voltage and the resistor is the load. The phase shift will be positive when the resistor is connected to the source. The lower the values of R and C, the higher the frequency bandwidth.With the resistor and capacitor connected in series and the two parts connected to a current source, the phase shift will be negative. At high frequencies, the output voltages is lower, and the circuit appears as a very low impedance. At low frequencies, the circuit looks more like a resistor. Again, the phase shift will be between 0 and 90 degrees.CommentThe correct term is phase angle, not 'phase shift'. By definition, the phase angle is the angle by which the load current leads or lags the supply voltage. For an RC circuit, the current leads the voltage, so the phase angle is a leading phase angle.
Why pf maintaining for ac only not in DC?
Power Factor measures the phase shift between current and voltage waveform. Since DC has no frequency there can be no phase shift.
Why does a phase shift occur in a ce transistor?
In any transistor circuit , there is a phase shift. It takes a finite time for the controlling signal, usually on the base connection, to have an effect on the circuit and cause a change to the output. The shape of the signal remains but it is shifted in time (phase). The difference varies by configuration. It can be as much as180 degrees if the circuit is inverting the signal. The addition of passive components add to the shift.
