QNEET-2018-Ph-890: NEET 2018 Physics - Class 12 NEET-2018-Ph-890 Solution: In a p-n junction diode change in temperature due to heating…
In a p-n junction diode change in temperature due to heating affects only reverse resistance affects only forward resistance does not affect resistance of p-n junction affects the overall V-I characteristics of p-n junction
Multiple Choice Options
- A affects only reverse resistance
- B affects only forward resistance
- C does not affect resistance of p-n junction
- D affects the overall V - I characteristics of p-n junction
Step-by-Step Verified Solution
As a result of heating, temperature increases
which generates large number of electron-hole
pairs which lead to increase in conductivity. As
current increases I = I 0 ( e _ q v K T ), overall resistance of
diode changes which affects forward and reversed
biasing.
