Question

The equivalent capacitance of the system shown in the following circuit is:

A

9 \mu F

B

2 \mu F

C

3 \mu F

D

6 \mu F

Step-by-Step Solution

  1. Missing Diagram: The problem requires a circuit diagram to determine the specific arrangement (series/parallel) of the capacitors.
  2. General Principles:
  • Parallel Combination: Capacitors connected in parallel have an equivalent capacitance Cp=C1+C2+C_p = C_1 + C_2 + \dots.
  • Series Combination: Capacitors connected in series have an equivalent capacitance given by 1Cs=1C1+1C2+\frac{1}{C_s} = \frac{1}{C_1} + \frac{1}{C_2} + \dots.
  1. Hypothetical Scenario: For an answer of 2 \muF2 \text{ \mu F}, a common configuration in such exams involving 3 \muF3 \text{ \mu F} capacitors is two capacitors in parallel (3+3=6 \muF3+3=6 \text{ \mu F}) connected in series with a third 3 \muF3 \text{ \mu F} capacitor. The equivalent would be 6×36+3=189=2 \muF\frac{6 \times 3}{6 + 3} = \frac{18}{9} = 2 \text{ \mu F}. Without the image, this is a likely theoretical derivation.
