JEE Main 2019 — Semiconductors Question with Solution

JEE Main 2019 (09 Jan Shift 2)

Question

Ge and Si diodes start conducting at 0.3 V and 0.7 V respectively. In the following figure if Ge diode connection are reversed, the value of V0 changes by: (assume that the Ge diode has large breakdown voltage)

Choose an option

Show full solutionCorrect option: B
Correct answer
B0.4 V

Step-by-step explanation

In first case, V0=12-0.3V=11.7 V

In second case, V0=12-0.7V=11.3 V

∆V0=0.4 V
