Sry sir... One question 🙋 ... Why electron flows opposite to current direction and hole flows same direction as current? My prof ask me and give me 2 hr to find ans? 🙆‍♂️

Sorry bt its late now... Conventionally it was believed that this charge is positive and this is negative. Charge never said I am positive or nagative. Then it was also believed that current goes from positive to negative termonal and all science developed around that. Later they realized that this the electron which flows in fact so they kept the science literature same and keep on doing it work with more conventions.
