Does the phrase direction of zero vector have physical significance?
No. the zero vector has no direction, therefore it has no significance.
What is the unit of a impidance?
Impedance is expressed in units of 'ohms'.In a DC situation, impedance is simply the scalar resistance.In a circuit where voltage/current have time-varying components,impedance is a complex quantity, with both magnitude and angle.
Physical significance of froude number in agitation?
the ratio of the tip speed of the impeller to the gravitational wave velocity should be greater than 1
How do you reduce the friction and vice versa?
Reduce the friction . . .Apply lubricant to the surfaces in contact, or reduce the mutual pressure.Friction the reduce . . .The phrase has no physical significance.
What is a measure of an object's ability to transmit electricity.?
Resistance (or impedance).
What is the significance of end correction?
The significance of end correction is that it is used in the radiation acoustic impedance of a circular piston.
What is significance of Hall coefficient?
physical significance of hall coefficient
What is the Physical significance of z transform?
t is the significance of Z-transform
Which is better high input impedance or low input impedance and why?
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
Does the phrase direction of zero vector have physical significance?
No. the zero vector has no direction, therefore it has no significance.
A list of words with the suffix ance?
There are so many words with the suffix ance. Some of them include trance, impedance, endurance, significance, dominance and many more.
How to distinguish between characteristic impedance and input impedance?
The characteristic impedance or surge impedance belongs to uniform transmission lines.In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Input impedance is greater than to load impedance?
In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
Is characteristics impedance of a filter is same as output or load impedance?
load impedance
What has the author I Drogin written?
I. Drogin has written: 'Physical testing- classification of physical tests and their significance'
What is analog audio impedance?
To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
What is high input impedance?
