E6A03 : Why does a PN-junction diode not conduct current when reverse biased?
A
Only P-type semiconductor material can conduct current
B
Only N-type semiconductor material can conduct current
C
Holes in P-type material and electrons in the N-type material are separated by the applied voltage, widening the depletion region
D
Excess holes in P-type material combine with the electrons in N-type material, converting the entire diode into an insulator
Correct Answer: Holes in P-type material and electrons in the N-type material are separated by the applied voltage, widening the depletion region
