Question

Which of the following p-n junction diodes is forward biased?

Options

• 

• 

• 

• 

Answer 1

Explanation:

For a p-n junction diode to be forward biased, the potential at the p-side (the triangle) must be higher than the potential at the n-side (the straight bar). Mathematically:

V_p > V_n

Since −1.0 V > −1.5 V, the p-side is at a higher potential, making it forward-biased.
