Two locations are said to be "in phase" when the waveform is "lined up" so there is no voltage difference between the two points.
They are out of phase if there is a voltage difference between them.
If you are looking at an oscillograph reading of both, if they are in phase the waveforms will be identical magnitude at the same time. If out of phase, one will be shifted relative to the other causing a voltage difference.
What else can I help you with?
Is a Chang in a phase a physical change or chemical Chang?
A change in phase is a physical process.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Is phase a physical or chemical property?
It is a physical property.
What are phase changes?
its physical changes
When water changes phase is it chemical or physical?
Physical, as it remains water.
Is there an Army regulation for no pt after phase two physical?
No, that is a myth. There is no regulation that states a Soldier cannot do PT after a Phase II physical.
When ethanol condenses and from the gaseous phase into the liquid phase is this a physical change or chemical change?
physical change- the composition of the ethanol is not effected
When alternating current flows through an capacitor current leads voltage by a phase angle of 90 degrees what is the physical interpretation of this phenomenon?
One interpretation is that if you take a capacitor that is not charged, it needs to take some current before any voltage appears across it. Therefore the current must precede the voltage.
When icicles form is it a physical or chemical change?
It is called a phase change.
When a substance changes from one physical form to another you say the substance has had a what?
When a substance changes from one physical form to another, you say the substance has had a phase change or undergone a phase transition.
Is a phase change an example of a physical or chemical or nuclear or a covalent change?
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
What is the transformation of a physical state of a substance into a different physical state?
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
