Electronic Devices Question 206

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} $ .
