Question

Submit Previous Answers Learning Goal To understand how to calculate capacitance, voltage, and charge for a combination of capacitors connected in series. X Incorrect: Try Again The correct answer does not depend on: Consider the combination of capacitors shown in the figure. (Figure 1) Three capacitors are connected to each other in series and then to the battery. The values of the capacitances are C 2C, and 3C, and the applied voltage is V. Initially, all of the capacitors are completely discharged; after the battery is connected, the charge on plate 1 is Q Part D Find the charge Qon the first capacitor Express your answer in terms of C and Submit Request Answer Part E Figure 1 of 1 Using the value of Q just calculated, find the equivalent capacitance Cq for this combination of capacitors in series Express your answer in terms of C 2C View Available Hint(s) Submit Provide Feedback

Explanation / Answer

part C)

1/Ceq = 1/C + 1/(2*C) + 1/(3*C)

Ceq = 0.545*C

charge on each capacitor, Q = delta_V*Ceq

= delta_V*0.545*C

now delta_V1 = Q/C1

= delta_V*0.545*C/C

= 0.545*delta_V <<<<<<-----Answer

D) Q = delta_V*0.545*C <<<<<<-----Answer

E) Ceq = 0.545*C <<<<<<-----Answer
