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 difference between analog phase shifter and digital phase shifter?
An analog phase shifter provides a phase shift with a varying control voltage. A digital phase shifter switches among phase states to provide discrete phase shifts. the more bits there are, the smaller the quantization/digitization error. For example, 1 bit phase shifter provides a phase shift of 0 and 180°, or 0 and 90°. 2 bit phase shifter provides a phase shift of 0, 90°, 180° and 270°. 3 bit phase shifter provides a phase shift of 0, 45°, 90°, 135°, 180°, 225°, 270°, 315°, 360°.
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
How to design a phase shifter circuit using operational amplifier to have a desired phase shift?
There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`. Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
Why phase shift oscillator uses three RC pairs?
The frequency stability of oscillators depend on the rate of change of phase with frequency. RC sections help improve the frequency stability. The net phase shift introduced by the RC feedback network is 180 degrees ,which contains n sections.Thus each RC section introduces 180/n degree phase shift. When 2 RC sections are cascaded due to low phase change rate the frequency stability is low. For 3 sections cascaded the phase change rate is high and hence there is improved frequency stability. However for 4 RC sections there is an excellent phase change rate resulting in the most stable oscillator configuration. But 4 RC sections increases cost and makes circuit bulky. Hence phase shift oscillators make use of 3 RC sections in which each section provides a phase shift of 60 degree. The latter is generally used in high precision applications where cost is not much regarded and only accuracy plays a major role.
What happens if capacitance is increased in parallel RC ciRCuit and series RC ciRCuit?
In both cases, the time constant of the RC circuit is increased. If the application is a high- or low-pass circuit, then the filter cutoff frequency is decreased in both cases. If the application is a phase-shift network, then the frequency for a given phase- shift is reduced.

Low-pass filter phase shift?
ONE low pass(RC) circuit gives 60 degrees phase shift
How can a tuned RC circuit improve the power factor of an inductive motor circuit?
The RC circuit can reduce the phase shift between the voltage and current in the power line. The phase shift is caused by the inductance of the motor. The phase shift between the voltage and current in the power line causes problems due to the presence of so called imaginary current or power that does no work but must be supplied by the power source.
Is a Boss PH-1 Phase Shifter good for an aggressive phase?
yes
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.
What is precision phase shifter?
A prescision phase shifter is use of circulr wave guide containing a lossless dielectric plate of length 21 called half wave (1800) section.
Can you use 3 phase circuit as 3 separate single phase circuit?
yes we can use as a single phase circuit because at practise directly the 3-phase circuit is made by combining the three single phase circuits
Compare the phase relationship between the voltage and current in a purely resistive circuit and an RL circuit?
In a pure resistive circuit the voltage and current are in phase. In an inductive circuit they are fro zero to 180 degrees out of phase. If they are in phase the Power Factor is 1 and 180 degrees the PF is zero. The exact amount of the phase difference depends on the specific circuit.
