How to Test Diodes with a Digital Multimeter is explained in this video.
In practice, no diode is an ideal one, it doesn't act as a perfect conductor when forward biased or as an insulator when reverse biased.A forward resistance is a small resistance that can be found in an actual diode.
It offers a high resistance when reverse biased and is called a reverse resistance.
The opposition offered by a diode to the forward current is known as forward resistance.The forward current can be constant, direct, or alternating.The forward resistance is classified into two categories.
DC forward resistance or static resistance is the opposition offered by a diode to the direct current flowing forward bias condition.The ratio of DC voltage across the diode to the DC current flowing through it is measured.
The graph shows that for the operating point P, the forward voltage is OA and the corresponding forward current is OB.The static forward resistance of the diode is given.
The AC forward resistance is the opposition offered by a diode to the changing current flow.It is measured by a ratio of the change in voltage across the diode to the current through it.
The AC forward resistance is determined by the forward voltages on both sides of the operating point and the corresponding forward current.
The resistance offered by the diode to the reverse current is known as Reverse Resistance.The reverse resistance of a diode should be infinite.The reverse resistance is not infinite because of the small leakage current caused by minority carriers.
The reverse resistance is larger than the forward resistance.The ratio of reverse to forward resistance is 1 for Silicon and 40 for germanium.
The language is easy to understand and analyze, thanks for the info.
The resistance of a crystal is a.c.The same as 2. more than 3. less than 4.
At 125o C, find the reverse resistance in k for an applied voltage of 3.6 V.
