Exam-style question
Try this first
What is the effect of increasing the temperature on the I-V characteristic of a diode?.
- A.The forward voltage drop decreases
- B.The reverse breakdown voltage increases
- C.The diode becomes more resistive
- D.The current remains unchanged
Model answer
What a good answer should say
- The forward voltage drop decreases
Explanation
Why this works
As temperature increases, the forward voltage drop across a diode decreases due to increased carrier concentration, allowing more current to flow at lower voltages.
