Semiconducting Devices Question 206

Question: The approximate ratio of resistances in the forward and reverse bias of the PN-junction diode is

[MP PET 2000; MP PMT 1999, 2002, 03; Pb. PMT 2003]

Options:

A) 102:1

B) 102:1

C) 1:104

D) 1:104

Show Answer

Answer:

Correct Answer: D

Solution:

Resistance in forward biasing Rfr10Ω and resistance in reverse biasing RRw105Ω

Therefore RfrRRw=1104
