A PN junction diode is a non-linear component and it consists of two junctions namely P-junction & N-junction where the majority and minority charge carriers are present like electrons and holes. It is also known as a semiconductor diode or PN junction diode. This diode includes two terminals namely anode and cathode, where a p-type semiconductor is an anode (positive voltage) and N-type semiconductors are cathode (negative voltage). The flow of current in the diode is in one direction only because it opposes in another direction with high resistance.

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 the significance of negative values of voltage and current?
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
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.
What is knee point voltage of current transformer?
10 % increase in voltage gives you 50 % increase in excitation current is called knee point voltage. To measure this first demagnetise the CT and apply voltage gradually from secondary keeping primary winding open circuited. while doing this above phenomeneo will be obsesrved.
What is knee voltage for silicon and germanium?
The knee voltage for silicon is approximately 0.7V, while for germanium it is around 0.3V. The knee voltage is the voltage at which a diode starts conducting significantly.
What is knee voltage and breakdown 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
What was the significance of wounded knee?
The wounded knee massacre is considered the ending of the "free Indian" in 1890.
What is knee voltage for GAAs?
Knee voltage, also known as threshold voltage, in Gallium Arsenide (GaAs) refers to the minimum voltage required to initiate significant current flow in a GaAs device, such as a transistor or diode. This voltage is crucial for determining the operational characteristics of GaAs-based electronic components. Typically, knee voltage in GaAs devices is lower compared to silicon counterparts, making GaAs favorable for high-frequency and high-efficiency applications.
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
