Question
Which of the following is a characteristic of a reverse-biased p-n junction?a.Very narrow depletion regionb.Almost no currentc.Large current flowd.Very low resistance
Solution
The characteristic of a reverse-biased p-n junction is b. 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 cross the junction, which leads to almost no current flow.
So, the correct answer is b. Almost no current.
