Question

In a reverse biased semi-conductor $p-n$ junction diode, if the depletion width doubles then it can be inferred that the

• A. reverse voltage have be removed .
• B. reverse voltage is one fourth of the previous value
• C. reverse voltage is doubled.
• D. reverse voltage is 4 times the previous value.

Answer 1

The correct option is D reverse voltage is 4 times the previous value.

$W\propto \sqrt{V_R}$
