Semiconducting Devices Question 284
Question: Before the saturation state of a diode at the plate voltages of 400 V and 200 V respectively the currents are i1 and i2 respectively. The ratio i1/i2 will be
Options:
A) $ \sqrt{2}/4 $
B) $ 2\sqrt{2} $
C) 2
D) 1/2
Show Answer
Answer:
Correct Answer: C
Solution:
Before saturation region, linear region comes.
In linear region $ i _{p}\propto V _{p} $
$ \Rightarrow \frac{i _{1}}{i _{2}}=\frac{{V _{p _{1}}}}{{V _{p _{2}}}}=\frac{400}{200}=\frac{2}{1} $ .
