In forward bias, how does the diode current vary with voltage?
AIt falls linearly
BIt rises exponentially
CIt stays constant
DIt cycles up, down
Answer & Solution
Correct answer: B. It rises exponentially
Forward current follows the Shockley relation and grows exponentially with the applied voltage.
