Physics Question on Semiconductor electronics: materials, devices and simple circuits
In a p−n junction diode, change in temperature due to heating
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
Answer
affects the overall V -I characteristics of p-n junction
Explanation
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.
