Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- In practice, no diode is an Ideal diode, this means neither it acts as a perfect conductor when forward biased nor it acts as an insulator when it is reverse biased.
- The opposition offered by a diode to the current flowing forward bias condition is known as its forward resistance.
- The forward resistance is measured by taking the ratio of DC voltage across the diode to the DC current flowing through it.
- The value of the forward resistance of a diode is very small, ranging from 1 to 25 Ohms.
- Under the Reverse biased condition, the opposition offered by the diode to the reverse current is known as Ideally, the reverse resistance of a diode is considered to be infinite.
