QNEET-2021-Ph-610: NEET 2021 Physics - Class 12 NEET-2021-Ph-610 Solution: The electron concentration in an n-type semiconductor is the…
The electron concentration in an n-type semiconductor is the same as hole concentration in a p-type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them. No current will flow in p-type current will only flow in n-type Current in n-type = current in p-type current in p-type > current in n-type current in n-type > current in p-type
Multiple Choice Options
- A No current will flow in p-type, current will only flow in n-type
- B Current in n-type = current in p-type
- C current in p-type > current in n-type
- D current in n-type > current in p-type
Step-by-Step Verified Solution
In N type semiconductor majority charge carriers are e _ and P type semiconductor majority charge carriers are holes.
I = neAV d = neA ( _ E)
As _ e > _ h _ I e > I h
