To meet the specification, one additional capacitor can be placed between the two points. (a) Should it be in series or in parallel with the 40.8 F capacitor? in series in parallel (b) What should be its capacitance? 0088 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. F (c) The next circuit comes down the assembly line with capacitance 38.7 F between A and B. To meet the specification, what additional capacitor should be installed in series or in parallel in that circuit? magnitude orientation in parallel Need Help?Read It essPractice Another Version Submit Answer Save Progress 9. 12 points SerPSET9 28.P.021.MI.SA My Notes This question has several parts that must be completed sequentially. If you skip a part of the question, you wil not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise A group of identical capacitors is connected first in series and then in parlel. The combined capacitance in

Explanation / Answer

(a)In series

The effective capacitance will be less.

(b)Let C be the capacitance.

1/39 = 1/40.8 + 1/C

1/C = 1/39 - 1/40.8 => C = 884 uF

Hence, C = 884 uF

(c)In parallel, to increase the capacitance.

38.7 + C = 39

C = 39 - 38.7 = 0.3 uF

Hence, C = 0.3 uF
