What is the phase shift from gas to a solid form?
solidification/sublimation
What is the voltage phase shift between primary and secondary line voltages in star-delta transformer connection?
The voltage phase shift between primary and secondary connections in a transformer is 180 electrical degrees.
Why capacitor is said to be a reactive component?
In electrical or electronic circuits, impedance can be said to have capacitive or inductive components. Capacitors cause capacitive impedance, and coils (chokes, transformers, loudspeakers, etc.) cause inductive impedance. A capacitor is said to be a reactive component in an AC circuit because it holds charge, then releases it, causing a phase shift in the output current. This phase shift in current equates to a phase shift between current and voltage. Reactive power is defined as a phase shift between current and voltage.
What is meant by Phase Shifting?
Phase shifting basically means moving the reference from where the wave starts along x axis. For example, sine wave and cosine wave are basically similar, but have different starting points along x axis. Therefore, it's clear that shifting a sine wave by 90 degree towards negative infinity will give cosine wave.
When are voltage and current out of phase?
Because the impedance of the inductor and capacitor is not a real resistance / has an imaginary value that causes voltage and current to be out of phase. An inductor's impedance is equivalent to j*w*L (j = i = imaginary number, w = frequency in radians, L = inductance), while a capacitor's impedance is 1/ (j*w*C). The 'j' causes the phase shift.
What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
How operational amplifier works as an oscillator?
A: Very easy to do just provide a positive feedback and/or a phase shift it will oscillate
What is the purpose of a phase-shift network in a Wien bridge oscillator?
A Wien bridge oscillator produces sine waves. In order for the sine waves to maintain a steady amplitude, a positive feedback system is used with some sort of control to limit gain. In order for the positive feedback system to work, the waves being "fed back" to the amplifier have to be in phase with the waves being generated. Thus, you need a phase shift network to ensure that the phases of the waves match, which in the case of a positive feedback system means that the generated waves need to go through a 360o phase shift during the feedback process.
What is the difference between wien-bridge oscillator and phase-shift oscillator?
Rc phase shift uses negative feedback.. Weinbridge uses both +ve and -ve feedback
Why do you use three R-C section in an RC phase shift oscillator?
To obtain a phase-shift of 180 degree.
How do you get phase shift in Hartley oscillator?
basicaly the two inductors work as an autotransformer,providing a phase shift of 180 degree
How do you derive three phase single way?
3 phase /sqrt(3) * 30 degree phase shift = single phase.
What is phase difference between input and output waveforms of ce amplifier?
180 degree phase shift
How do you surpres 3rd harmonics?
you match the frequencies but with a 90 degree phase shift
Why is the R-C oscillator also called a phase shift oscillator?
The R-C oscillator is also called a phase shift oscillator because the R-C filter creates a phase shift from input to output. The feedback portion of the oscillator (an amplifier) then serves to pump energy back into the filter.
What happens if two phases short with one phase with phase shift of one degree?
guess the fuse would blow
Viva questions for RC phase shift oscillator?
A phase-shift oscillator is a simple electronic oscillator circuit. It consists of an inverting amplifier element such as a transistor or op amp, with its output fed back into its input through an filterconsisting of a network of resistors and capacitors. The feddback network 'shifts' the phase of the amplifier output by 180 degrees at the oscillation frequency, to give positive feedback.[1] Phase shift oscillators are mostly used at lower frequencies, often in the audio frequency range as audio oscillators.
