# 9702 CIE Physics Paper 11 watch

1. How was it? i did not find it entirely difficult, just too little time to carry out all the calculations? What did you guys get for the energy dissipated question?
2. chargexpotential difference
4. (Original post by pencil-case)
didn't get time to do it took a wild guess.
5. (Original post by pencil-case)
chargexpotential difference
same, though apparently the energy dissipated is equal to the power which is potential difference x current. was a tricky question.

power is rate of energy dissipation. was there any time given in the question? if its in a second its the same anyway

P = IV P = W/t W = QV Q = It so W = IVt
