Combination of Capacitors

The total charge on the system of capacitors C1=1 μF,C2=2 μF,C3=4 μFC_1 = 1\ \mu\text{F}, C_2 = 2\ \mu\text{F}, C_3 = 4\ \mu\text{F} and C4=3 μFC_4 = 3\ \mu\text{F} connected in parallel is:

(Assume a battery of 20 V20\text{ V} is connected to the combination)

Show answer and solution

Answer: (a)

  1. Parallel: C=1+2+4+3=10 μFC = 1 + 2 + 4 + 3 = 10\ \mu\text{F}.
  2. Q=CV=10×20=200 μCQ = CV = 10 \times 20 = 200\ \mu\text{C}
  3. So the answer is (a) 200 μC200\ \mu\text{C}.
