Question

Fill in the blanks.
In potential barrier of p-n junction, positive charges tend to seek regions of ____ potential whereas negative charges tend to regions of ______ potential

• A. low, high
• B. high , low
• C. high , high
• D. low low

Answer 1

The correct option is A low, high

In potential barrier region, the majority carriers from one side of junction cross the junction to reach the other side where they are minority carriers. Hence holes(positive carriers) seek the p-region(low potential region), and electrons seek the opposite.
