NEET 2018, Physics Q20: Semiconductors, p-n Junction Diode and Applications
NEET2018Paper 2018Physics
Q.
In a p-n junction diode, change in temperature due to heating
- A
Affects only reverse resistance
- B
Does not affect resistance of p-n junction
- C
Affects only forward resistance
- D
Affects the overall V - I characteristics of p-n junction
Solution
Due to heating, number of electron-hole pairs will increase, so overall resistance of diode will change.
Due to which forward biasing and reversed biasing both are changed.
