Question

Which voltage pair corresponds to a forward-biased p-n junction diode? In each option the first value is the p-side potential and the second is the n-side potential.

G1 Physics · Accepted Answer

A p-n diode is forward biased when the p-side is at higher potential than the n-side. Only +2 V on p and −2 V on n satisfies this. Correct answer: D.
