1. The problem statement, all variables and given/known data Two cylindrical resistors are made from the same material and have the same length. When connected across the same battery, one(A) dissipates twice as much power as the other(B). Find ratio of dA/dB. 2. Relevant equations P = VI = V2/R = I2R Area of cylinder = 2πrh + 2πr2 3. The attempt at a solution I tried to find what the radius would be and managed to get 2 for A and 1 for B so r2 is 4 and 12 is 1 so 4/1, but that is wrong. I am confused on how to approach this problem.
