You have two identical capacitors. They can be connected in series or parallel. If you want the smallest equivalent capacitance for the combination, how should you connect them?
Correct answer: B. In series
- A. In parallel
- B. In series
- C. Either way because both combinations have the same capacitance
- D. We can not determine, because presence of resistance in the circuit determines capacitance
Explanation
In series, the net capacitance of the capacitors is less than the individual capacitances. Ct = 1/C1 + 1/C2 + 1/C3Thus any values for C1, C2, and C3 will become less than the original as they are each divided by 1.

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.
