Which one of the following represents forward bias diode?
Explanation
Forward bias: p-side potential higher than n-side.
Detailed Solution
In forward bias, the p-type semiconductor is at a higher potential with respect to the n-type semiconductor.
Only in the first circuit is the p-side (0 V) at a higher potential than the n-side (–2 V), so it is forward biased.
