Good quiz! And I have a much better chance at this one than the lyrics to a Miley Cyrus song.

Question #8 is wrong. Conventional Theory is the movement of the negative charge as opposed to electron theory which is the movement of the electrons.

Conventionally, current is movement of positive not negative charge. But in actual fact it is d electrons(negative charge) dat do d movement

I got 10/10, but also I think #8 is too ambiguous. Just because I got the answer correct does not make it right...
