What is the phase shift between voltage and current when an capacitance is connected to the circuit?
The amount of phase shift depends on the resistance that is also present in the system. In an ideal situation, the phase shift would be +90 degrees, but that would require a voltage source with zero resistance, conductors with zero resistance, and an ideal capacitor that exhibited only capacitance.
For AC circuits what is meant by the term in phase?
Both the current and voltage are represented by sine waves. In a pure resistive circuit the current and voltage wave forms would have the positive and negatives peaks and zero crossings perfectly aligned with the other waveform. If they were 180 degrees out of phase the positive cycle peak of one would align with the negative peak of the other and would be producing zero power. In between a zero and 180 degree phase shift the Power Factor would range from 1 with zero phase shift to zero with 180 degree phase shift.Power = Current x Voltage x Power Factor.Another AnswerFor a three-phase supply, the term 'phase' describes any one of the armature windings; for a three-phase load, the term 'phase' describes any one of the three loads. The three energised conductors that join the load to the supply are called 'lines'.So phase voltages are the voltages appearing across individual armature windings or loads, whereas line voltages are the voltages appearing across a any pair of line conductors.
How many degrees of current flow is there in a sine wave?
If you have V = 120Vrms Cos(2*pi*60t + 120). The magnatude of the voltage is 120Vrms. The frequency is 60Hz. The phase shift is 120. That would be the voltage that comes out of a standard American household eletrical outlet. The current would depend on what is plugged into the outlet. A general equation would be VmCos(w*t + theta) or ImCos(w*t + theta) for current. To use a Sine wave, just do a 90 degree phase shift. (sin(t) = cos(t-90) or cos(t) = sin(t+90))
What is the difference between the voltages in the coils A and B in three phase generator?
I assume that you are referring to phase A and phase B? So what happened to phase C, in that case? The answer is that the magnitudes are the same, but phase B (and phase C) are displaced by 120o. The normal phase sequence (the order in which each voltage would reach its peak value) would be A-B-C.
What state of matter can be used in hydraulic systems?
State? Or phase? It would be a liquid phase. But its state is unknown since the state of a substance includes its pressure, temperature AND phase. Phase is a part of a state, but a state is not a phase.
What happens if two phases short with one phase with phase shift of one degree?
guess the fuse would blow

Which signaling systems would you recommend for a situation in which bandwidth is limited and noise interference is a consideration?
Phase shift keying Quadrature shift keying
Difference between line transformation ratio and transformation phase ratio?
line transformation ratio would be the turns ratio (ie voltage ratio), while the phase transformation ratio is most probably the phase shift introduced by a 3 phase transformer.
Device for connecting two or more computers by phone?
That would be called a Modem. A Modem is an acronym for MOdulator, DEModulator. There are two technologies used for computer modems; tone shift and phase shift. Tone shift takes the ones and zeroes and turns them into tones, and support speeds up to 9600 baud (9600 bits per second, roughly). Phase shift takes the ones and zeroes and turns them into phased tones, and supports speeds of up to 56KBaud (56 thousand bits per second).

Describe in brief the type of power factor improvement system?
You want a power factor of 1 or 100%, which is a purely resistive circuit. If you have a motor or some other inductive load in a circuit the total voltage and total current in the circuit will not be in phase (phase shift), your power factor will be less than 1. By adding a capacitor (180 degrees out of phase with inductive load) to the circuit that has a capacitive reactance equal to the inductive reactance of the motor, you can cancel the phase shift and have an ideal power factor (no wasted power). Anything above .9 would be good.
How would you explain how the readings on a bathroom scale change as you shift your weight gradually from side to side?
the weight is not evenly distributed so it gets an average of sides and gives you that number
Will a 1997 Dodge truck automatic transmission fit a 1995 Dodge truck?
It would bolt up, but it will not shift. The shift control systems are different.It would bolt up, but it will not shift. The shift control systems are different.
What phase is water in if it is found as a glacier?
the phase would be solid.
Is 3 phase motor run on 1 phase supply?
No. That would be a single phase motor.
