The depletion layer has large electrical resistance because: |
It contains few ions as charge carriers. It has few holes as charge carriers. It has no charge carriers. It contains few electrons as charge carriers. |
It has no charge carriers. |
The correct answer is Option (3) → It has no charge carriers. In the depletion region, there are no free electrons or holes to conduct current. Instead, it contains immobile charged ions. This lack of free charge is why the depletion region has high electrical resistance. |
