Why can electrons cross a forward-biased junction?
AThe barrier is narrow enough
BElectrons lose their charge
CNo holes remain there
DThe barrier is much wider
Answer & Solution
Correct answer: A. The barrier is narrow enough
Forward bias shrinks the depletion region so electrons can get across into the p-side.
