You have three capacitors, each of 2µF. In which of the following combinations of the three capacitors is the resultant capacitance 6µF?
Correct answer: D. All three capacitors are in parallel
- A. All three capacitors are in series
- B. Two capacitors are in series, one in parallel
- C. Two capacitors are in parallel, one in series
- D. All three capacitors are in parallel
Explanation
When capacitors are connected in parallel, the equivalent capacitance is the sum of the individual capacitances.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
