The reverse saturation electric current of a pn junction varies with temperature (t) as
Answers
In a reverse bias pn diode…the reverse bias current is generated due to diffusive flow of electrons of p side into n side and diffusive flow of holes of n side to p side..hence minority carrier flow…majority carrier cannot flow in reverse bias since holes of p are attracted towards -ve terminal of battery and electrons of n side are attracted by +ve terminal of battery…
Hence the only current is reverse saturation current due to minority carrier flow…and this is in the range of uA to nA….
These carriers are independent of reverse bias voltage but is dependent on temperature, doping concentration…reverse saturation current doubles per 10 degree rise in temperature
Answer:
reverse saturation current of a pn junction varies with temperature
it increases temp also increases
Explanation:
as temp. increases,election hole pair more formed.so Conductivity increases thus current increases
hope you understand
