I don't remenber the question as this happened in 1st or second sem. (I'm currently at the end of 5th sem.). It was related to radiation and we had to find the incoming rate of electrons for some provided conditions.
After his statement I asked him what would be the rate of incoming electron if 3 electrons arrived in 2 seconds. He was like [IMGG]*www.larryberkelhammer.com/wp-content/images/Sad-dog-face.jpeg[/IMGG]
He got confused. Probably because he mixed up electrons with charge quantization. Which means he needs to review everything about electronics that he's studied.
