When capacitors are connected in series, the equivalent capacitance is given by:1/Ceq = 1/C1 + 1/C2When capacitors are connected in parallel, the equivalent capacitance is given by:Ceq = C1 + C2From the given information, we have:1/120 µF = 1/C1 + 1/C2480 µF = C1 + C2Solving these equations, we get:C1 = 240 µFC2 = 240 µF
