Question

Three capacitors are in series: C1 = 15uC , C2 = 55uC , and C3 = 85uC . The series combination is connected across a 24V battery.


Find the charge on the capacitor C1. on C2 and on C3 (individually)

Compute the energy stored in the capacitor C1. on C2 and on C3 (individually)

please detail your steps and provide the final answers for the questions.

thank you

Explanation / Answer

Equivalent Capacitance = C =>1/C = 1/C1 + 1/C2 + 1/C3 =>C = C1C2C3/(C1C2+C2C3+C3C1) = 10.35055351uC As they are in series all will have same charge. Q = CV = 10.35055351*24 = 248.4132841uC Energy stored on each capacitor = Q^2/2C = 2980.95941
