(C) Peak inverse voltage
(D) all of these
Answers
Answer:
In semiconductor terminologies and operation,
The forward voltage at which the current through the junction diode starts to increase rapidly is known as _Knee voltage_.
Hope this helps you !
Correct option is (A) Knee voltage
Till the knee voltage, the current in a semiconductor increases slowly. After Knee voltage, the current increases rapidly for a small change in the voltage. The forward voltage at which the flow of the current during the PN Junction of the diode begins increasing very quickly is commonly known as knee voltage. This voltage is also known as cut-in voltage.
In forward characteristics of the diode, if we notice the graphical representation, conduction begins to increase rapidly is looks like or leg but technically it is known as Cut in voltage.
