The relation used to find the equivalent capacitance for the given combination of capacitors is
Correct answer: D. 1/C1 + 1/C2 + 1/C3
- A. C1 + C3
- B. 1/C1 + 1/C2
- C. C1 + C2 + C3
- D. 1/C1 + 1/C2 + 1/C3
Explanation
The correct answer is1/C1 + 1/C2 + 1/C3This formula is used to calculate the equivalent capacitance for capacitors in series. In a series combination, the reciprocal of the total capacitance is the sum of the reciprocals of the individual capacitances. The other options are incorrect:C1 + C3and1/C1 + 1/C2are incomplete or incorrect representations, andC1 + C2 + C3is the formula for capacitors in parallel, not series.

About Capacitors
Capacitors store electric charge and energy in an electric field between conductors. Work includes capacitance, the relation Q = CV, dielectric materials, charging and discharging, energy formulas, and combinations of capacitors in series and parallel. Electric potential difference is needed to understand why charge and stored energy change.
