Question

Problem 5. (4 points) This is NOT a multiple-choice problem! A capacitor network and Kirchhoffs rules. Four capacitors are connected to a battery as shown in Fig. 2. Their capacitors are G = 1 pF, C2-2 pF, C3-3 pF, and C4-4 pF. Rank the capacitors according to the charge they store from largest to smallest. Answer: Note: Answer should includeor'or'-', for example, Qi > Q2-03 > Q, where Q is a symbol of the charge on a capacitor.) Cr C4 Figure 2. A capacitor network with four capacitors and a battery.

Explanation / Answer

Charge on C1 and C3 has to be equal because they are in same branch. Similarly charge on C2 and C4 are equal.

C2 and C4 as combination have higher charge than C1-C3 combination, so the former has more charge.

Q1 =Q3 < Q2 = Q4
