1. The problem statement, all variables and given/known data In the circuit shown in the figure the voltage of the battery is 15.0 V, and the capacitors have the following capacitances: C1 = 2.32 mF, C2 = 2.25 mF, C3 = 4.85 mF, C4 = 4.89 mF What is the equivalent capacitance of the four capacitors? http://tinypic.com/r/24dn5oi/8 Two sets of series capacitors that are parallel to each other 2. Relevant equations Ceq=(1/C1+1/C2+1/C3...)^-1 ---- series Ceq=(C1+C2+C3...) --- parallel 3. The attempt at a solution Ceq=(C1+C3)(C2+C4)/(C1+C2+C3+C4) =(7.17)(7.14) / 14.31 = 3.58 mF According to online hw system, it's wrong. Is my equation incorrect?
