What is the I-V characteristic of a diode when forward-biased?.
- A.Current increases exponentially with increasing voltage
- B.Current remains constant regardless of voltage
- C.Current decreases as voltage increases
- D.Current increases linearly with voltage
Model answer
What a good answer should say
- Current increases exponentially with increasing voltage
Explanation
Why this works
In a forward-biased diode, the current increases exponentially as the voltage increases, which is characteristic of diode behavior. This is due to the diode allowing current to flow easily after a certain threshold voltage is reached.
