I am having a lot pf problem to attempt this question, please help me, i am stuck..!!!!!! The power loss P in a resistor is calculated using the formula p=v^2/R The uncertainty in the potential difference V is 3% and the uncertainty in the resistance R is 2%. What is the Uncertainty in P? A/ 4% B/ 7% C/ 8% D/ 11% Hmmm My attempt: Fractional error = in V, 0.09 and in R 0.2 i subtracted and i got 0.11 that is 11% ANSWER D And i can be at 98% sure that the answer is not correct as uncertainty cannot be substrate d ..??? please help me to attempt the question !!!!!!!!
