Two capacitors, C1 = 25 µF and C2 = 6.0 µF, are connected in parallel and charged with a 150 V power supply. (a) Calculate the total energy stored in two capacitors. energy stored = 1/2C(deltaV)^2 or Q^2/2C I been doing this and its marking me wrong. first i found both charges which is Q = VC C1 = 3750 uC C2 = 900 uC then i did 3750^2/2(25) = 281250 900^2/2(6) = 67500 i add both up and get 348750 J It is saying my answer is incorrect and i did this problem 3 different way getting the same number. does this look like a system error or is my number really off.
