Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
What is 0.37v and 0.63v in RC circuit?
0.63 is the knee voltage & 0.37 is the cutoff voltage
What is the Difference between Si and Ge diodes?
The significant operational difference between a Si diode and a Ge diode is that Si diodes have a knee voltage of 0.7V needed to allow current flow and Ge diodes have an operational voltage of 0.3V to allow current flow.
What happens to the current when the voltage becomes limited at the knee?
A: Perfect example is a zener. As input voltage increases the current at the knee increases almost linearly at the zener voltage. If the inputs varies up or down then the current will vary up or down at the preset voltage making a zener a voltage regulator because of this feature
Why the graph of breakdown voltage is cheaper than knee voltage?
Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.
What is knee voltage and breakdown voltage?
Knee voltage (cut in voltage) :-The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage Breakdown voltage :-It is the minimum reverse voltage at which the P-N Junction can conduct without damage to the current
What is meant by cut in voltage in diode?
Cut in voltage (Knee voltage): The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage.
What is knee voltage of transistor?
The knee refers to the shape of the curve when plotting voltage vs current in forward biased semiconductor junctions. Knee voltage, or threshold voltage, varies with device construction, doping level, and operating temperature among other parameters. This is due to the bandgap at the PN junctions of the diode. Therefore, even when forward biased, little current will flow until the diodes threshold voltage is exceeded. Threshold voltages for common silicon diodes is approximately 0.7V, and for Schottky devices near 0.3V. Germanium based diodes exhibit lower voltage thresholds than silicon based diodes, but are less common due to other limitations. All diodes also exhibit a reverse bias breakdown. Engineers normally avoid operation small signal and rectifier diodes in this mode by selecting a device with a reverse voltage specification much higher than expected voltages. However; zener diodes are specially constructed and doped to produce a relatively low reverse breakdown voltage which is commonly used in shunt regulators and overvoltage protection circuits. Various values of zener voltage are available.
What is the primary difference between a zener diode and PN-junction Diode?
ZENER DIODE IS MADE TO REVERSE BREAK OVER AT A CERTAIN VOLTAGE the break over knee is not exactly sharp especially in low voltage zeners. and p-n means positive and negative junction
Knee pont voltage- briefly distinguish?
The knee point voltage of a CT is the voltage at the "knee" of a I-V characteristic (if you increase voltage, and plot this voltage with respect to the current flow, you will see a logorithmic type response). The knee is usually specified as 10% distortion (ie, the voltage is 10% less than you would expect relative to the current flow). beyond the knee point, the CT is considered in saturation. This applies to amplifiers / transistors as well as CTs. Transistors used as ampifiers are operated in the "linear region", or the region below the knee point of that particular transistors I-V characteristic.
Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
What is the value of the knee voltage and breakdown voltage of z?
It is about 0.7 volt for Silicon diodes.
What is 0.37v and 0.63v in RC circuit?
0.63 is the knee voltage & 0.37 is the cutoff voltage
Why the knee voltage for germanium is 0.2v?
That is the property of that material.
What is the difference between girls stockings and girls knee high socks?
practically speaking , its the same thing as long as the socks reaches at least the knee. if its lower than the knee its called a high socks
What is the difference between breeches and jodhpurs?
Breeches only go down to the knee, jodhpurs are full legnth.
What is the difference between the joints at shoulders and knees?
yes the knee joint is stronger
