QAIPMT-2005-Ph-2528: NEET 2005 Physics - Class 12 AIPMT-2005-Ph-2528 Solution: When a wire of uniform cross-section a length l and resistance…
When a wire of uniform cross-section a length l and resistance R is bent into a complete circle. resistance between any two of diametrically opposite points will be R/4 4R R/8 R/2
Multiple Choice Options
- A widens the depletion zone
- B increases the potential difference across the depletion zone
- C increases the number of donors on the n side
- D decreases the electric field in the depletion zone.
Step-by-Step Verified Solution
Number of donors is more because electrons
from �ve terminal of the cell pushes (enters)
the n side and decreases the number of
uncompensated pentavalent ion due to which
potential barrier is reduced. The neutralised
pentavalent atom are again in position to
donate electrons.
