negative resistance उदाहरण वाक्य

The negative resistance of the diode excites microwave oscillations in the cavity which radiate out the hole into a waveguide " ( not shown ) ".
For a mechanical analogy to negative resistance behavior, and how a ballast can limit current, imagine trying to push a heavy weight across a smooth surface.
The negative resistance can be used to generate electrical oscillations and waveforms, as in the relaxation oscillator whose schematic is shown in the picture on the right.
Alas . . . there was no response . . . Then I began creating and filling the missing introductory article sections starting with this unlucky Negative resistance.
The negative resistance operating region of the tetrode is exploited in the dynatron oscillator, which is an example of a negative resistance oscillator . ( Eastman, p431)

Therefore, there is no real " negative resistor " analogous to a positive resistor, which has a constant negative resistance over an arbitrarily wide range of current.
Hysteresis is due to the bulb's negative resistance, the fall in voltage with increasing current after breakdown, which is a property of all gas discharge lamps.
The " I V " curve, including the negative resistance region, lies in the 1st and 3rd quadrant of the plane so the device has positive static resistance.
If an inductor is connected to the input, the circuit will oscillate if the magnitude of the negative resistance is greater than the resistance of the inductor and any stray elements.
