electrical impedance

The main and coupled line are of the system impedance.

A step down in impedance would be the mirror image of figure 4(a).

When the two impedances are the same the bridge will be balanced.

Impedance should not be too low for desired fault current.

Impedance is the opposition by a system to the flow of energy from a source.

The impedance to ground of both legs is the same and the line remains balanced.

In electronics, would represent an impedance, which is independent of time.

The starting point here is the image impedances of the L section in figure 2.

In the general case can be selected to produce any value of negative impedance.

They are designed to have an impedance of 50 ohms.

A more complex example of stepped impedance design is presented in figure 6.

In order for the impedance matching ear to work, certain conditions had to be met.

Similarly, even in the darkness, it provides little impedance to his hands or body.

Advantage: Higher impedance values can be reached using the same number of components.

The concept of electrical impedance is perhaps the most commonly known.

Each type of transmission line has a specific characteristic impedance.

For the relationship between the electric and magnetic fields, see the impedance of free space.

Impedance changes at the fault location make measuring more difficult.

One man was sent down the tracks until he found the impedance trip sensor.

The scheme presented in the table is known as the impedance analogy.

The cable used must have the same characteristic impedance as the component.

This is a particularly important transform for finding equivalent impedances.

The output impedance cannot be controlled other than through feedback.

For example, a flat metal sheet always has low surface impedance.

Any amplifier will drive more current to a lower impedance load.

The concept of electrical impedance is perhaps the most commonly known.

It is only necessary that the electrical impedances are symmetrical.

The two main sensors used are light detectors and electrical impedance.

Electrical impedance is a measurement of how electricity travels though a given material.

Every tissue has different electrical impedance determined by its molecular composition.

This is important since it balances electrical impedances between phases of a circuit.

The meaning of electrical impedance can be understood by substituting it into Ohm's law.

This is the mathematical formulation of electrical impedance tomography.

Reactance is the imaginary part of the complex electrical impedance.

From these recordings, one can calculate the electrical impedance of the muscle at a given input frequency.

This is usually accomplished by providing multiple interconnected pathways of low electrical impedance to the ground.

Terminal Electrical impedance in axial mode ranges between 100 and 200 ohms.

In the series configuration, resonance occurs when the complex electrical impedance of the circuit approaches zero.

First consider the Electrical impedance of the series LC circuit.

Under these conditions the line current is very small because of the high electrical impedance of the parallel circuit at antiresonance.

In alternating current circuits, electrical impedance is also measured in ohms.

An example of this is their electrical impedance, which varied across the audio spectrum by a ratio of more than 100:1.

Measurement of electrical impedance to obtain physiological or diagnostic information has been of interest to researchers for many years.

Electrical impedance, like resistance, is expressed in ohms.

There are also challenges in presenting to the amplifier an electrical impedance which is approximately constant at all frequencies.

Analogous to electrical impedance, magnetic impedance is likewise a complex variable.

He first proposed the idea of electrical impedance tomography as a medical imaging technique in a publication in 1978.

This method measures the electrical impedance.

In addition, digital horn analyzers are able to determine the electrical impedance of piezoelectric materials.

This writing using complex numbers is the same as the writing used with phasors or Electrical impedances.
