A) For positive charge carrier current flows from higher potential to lower potential. While for negative charge carrier, it flows from lower to higher potential
B) For both positive and negative charge carriers current flows from higher to lower potential
C) For both positive and negative charge carriers current flows from lower to higher potential
D) For negative charge carriers current flows from higher to lower potential while for positive charge carrier it flows from lower to higher potential
Correct Answer: B
Solution :
Current always flow from higher potential to lower potential and is not depending on whether positive or negative charge carriers are moving. Though positive charge always move from high to low potential region while negative charge carriers move from low to high potential region.
