Question E6A03
From subelement E6 - E6A
E6A03
Answer: CWhy does a PN-junction diode not conduct current when reverse biased?
AOnly P-type semiconductor material can conduct current
BOnly N-type semiconductor material can conduct current
CHoles in P-type material and electrons in the N-type material are separated by the applied voltage, widening the depletion region
DExcess holes in P-type material combine with the electrons in N-type material, converting the entire diode into an insulator
