What is a electrical lengthener?
An electrical lengthener is a device or circuit used to increase the effective electrical length of a transmission line without physically extending the physical length of the line. This can help in matching impedance, reducing signal delays, or improving the performance of the transmission line.
How does a hairdryer work with electricity?
Electrical heating element, electrical blower - blows hot air.
Can impedence inversion be obtained by a short circuit stub?
No, impedance inversion cannot be achieved with a short circuit stub. A short circuit stub will have a low impedance at the point where it is connected, which will not invert the impedance at that point. Impedance inversion can be achieved using techniques such as a quarter-wave transformer or a transmission line with specific impedance characteristics.
What is a condition for resonance for an electrica circuit with reactive element?
For resonance to occur in an electrical circuit with a reactive element, the reactive element's reactance needs to be equal and opposite to the circuit's impedance. This occurs when the capacitive and inductive reactances cancel out, resulting in a net impedance that is purely resistive. At this point, maximum current flows through the circuit, enhancing certain frequencies.
What do Two circuits that are equivalent have the same of?
If the two circuits have the same input impedance they are equivalent in respect of the input impedance.
What is impedance analyzer?
Measurement of electrical conductivity by knowing the impedance value.
What is used to measure impedance?
an ohm meter concerning electrical impedance
Bio electrical impedance works off the principle of?
Electrical Flow
Impedance is measured in what?
AnswerThe unit of measurement for impedance is the ohm.
What is the difference between characteristic impedance and intrinsic impedance?
I believe intrinsic impedance is more tied to the medium, thus is defined in terms of magnetic and electric permeability and electrical conductivity, while characteristic impedance is a "wider" look at the impedance. For example, you can calculate the intrinsic impedance of a 18 awg copper wire, or air, or a vacuum. If you wanted to use coax cable with an 18 awg core, you would be looking at the characteristic impedance, not the intrinsic impedance of the copper that will be carrying the waveform.
What does impedance in ham radio mean?
Impedance is not unique to ham radio and applies to all electronics. Impedance is a property of electrical circuits that can impede the current from flowing.
What electrical quantity consists of both resistance and reactance?
Impedance.
What is impedance phlebography?
Impedance phlebography is a noninvasive test that uses electrical monitoring to measure blood flow in veins of the leg.
What has the author B Dewberry written?
B. Dewberry has written: 'A review of electrical impedance spectrometry methods for parametric estimation of physiologic fluid volumes' -- subject(s): Spectrometers, Physiological responses, Impedance measurement, Cardiovascular system, Microgravity, Electrical impedance
What is Transfer-impedance?
transfer impedance is impedance we encounter when an electrical current passing through one element of the system makes a voltage difference in other element of same system. eg:shield in a coaxial cable
What means 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.
Who is ohm?
Ohm is the SI unit of electrical impedance (AC) or the electrical resistance (DC), named after Georg Ohm. Not Ohms!
