Question
Which of the following is a characteristic of a reverse-biased p-n junction?a.Very narrow depletion regionb.Very low resistancec.Almost no currentd.Large current flow
Solution
The characteristic of a reverse-biased p-n junction is c. Almost no current.
Here's why:
In a reverse-biased p-n junction, the p-side is connected to the negative terminal of the battery and the n-side is connected to the positive terminal. This increases the potential barrier and widens the depletion region. As a result, it becomes difficult for the majority charge carriers to overcome this increased potential barrier, hence almost no current flows through the junction. This is in contrast to a forward-biased p-n junction, where the potential barrier decreases and current easily flows through the junction.
