Forward Bias

Forward bias reduces barrier allowing:
Select the correct option:
Solution
Incorrect! Answer:
Increased majority carrier flow
In forward bias, the positive terminal of the battery is connected to the p-side and negative to the n-side.
- The applied voltage opposes the built-in barrier potential (V0).
- This reduces the width of the depletion layer and the effective barrier height (V0−V).
- As a result, many more majority carriers (holes from p, electrons from n) gain enough energy to cross the junction, resulting in a large current that increases exponentially with voltage.
