How to use Impedance in a sentence
However the electrolyte is potassium hydroxide, which is very conductive, resulting in low internal impedance for the cell.
In this picture the normalized impedance of the SMITH chart is 200 ohms.
Given the volume velocity, the PC also calculates the input impedance according to equation 2.7.
Standard structured UTP or FTP cabling systems have a nominal impedance of 100 ohms.
Having a high input impedance means it only takes very little capacitive coupling to get a reading.Advertisement
Therefore it is possible to directly measure the specific acoustic impedance at the cone surface.
Now we see why coaxial cable is often designed to have 75 ohms characteristic impedance.
Weighing people under water and measurements of electrical impedance have also been employed.
The floors of the building present an extremely low impedance to water.
T Adds a transmission line of characteristic impedance z in series with the impedance z in series with the impedance in X, transforming its impedance in most cases.Advertisement
In common with most good Yagi designs, these antennas are ' matched ' to the standard 50 ohms input impedance of radio-tracking receivers.
You will be told the exact value of the output impedance.
This lower load impedance being presented to the inverter causes more power to be sourced from the inverter.
The peak primary current can be found by dividing the " fully charged " capacitor voltage by the surge impedance.
Also included within this test is a polarity and earth fault loop impedance test of up to 10% of the sockets.Advertisement
This component has, by the pure fact it is two mutually coupled inductors, impedance.
They were characterized via scanning electron microscopy, complex impedance measurements, electron probe microanalysis and dielectric lifetime testing.
They will only be effective for certain soil types, where a sufficient impedance mismatch with concrete for the wall can be achieved.
The dipole has a built-in transformer to match the 72 ohm balanced terminal impedance to 50 ohm unbalanced (balun) feeder cable.
High Impedance Mic A microphone designed to be fed into an amplifier with input impedance greater than 20 k ohms.Advertisement
Microphone Input The SWP123 includes a high quality microphone preamplifier and features an XLR connector for easy connection to low impedance, balanced microphones.
Impedance transformation and matching, microwave networks, cavity resonators, antennas and propagation are also covered.
Electrical impedance tomography a new imaging technique for epilepsy All imaging methods in use today have their limitations.
The changing nature of electrical installations is reducing their natural impedance, so that higher short-circuit currents occur.
Analysis of nonlinearities of plasma harmonics and sideband noise which are uniquely related to dynamic complex impedance and chemistry.Advertisement
Do not remove any of the tantalum beads in the Digital section, these provide extra low impedance smoothing.
In this case the originally purely imaginary impedance of the undersized waveguide obtained a real part and the barrier was annihilated.
The impedance of the primary or alternator circuit is so adjusted that when both the chokers are in circuit the current flowing is not sufficient to charge the condensers; but when one choker is short-circuited the impedance is reduced so that the condenser is charged, but the alternating arc is not formed.
An improvement in this respect has been effected by the insertion of condensers in the cord circuits, coupled with the use of two sets of impedance coils, one set on each.
The impedance coils shown connected between the battery and the lines and between the latter and the transmitters are joined up non-inductively as regards the transmitter circuits, but inductively as regards the secondary circuits.
A cord circuit, similar in many respects, including the method .y.^9 Jr '' of operation, but equipped with condensers and impedance coils, in place of the repeating coil, is shown in fig.
It was originally the practice to place the calling apparatus in series in the line circuit, but the effect of the large impedance introduced by the electromagnets of the call XXVI.
Although the bells are constantly in circuit their high impedance prevents any appreciable interference with the telephonic currents.
Figure 2 - Below the first series resonance, the impedance depends on the total capacitance of the planes.
