PHY 102 Capacitors and Capacitance Objective Question

Question

Three capacitors C₁, C₂, C₃ are connected in series. What is the equivalent capacitance?
Options
A C_eq = C₁ + C₂ + C₃
B 1/C_eq = 1/C₁ + 1/C₂ + 1/C₃
Correct Answer
C C_eq = (C₁C₂C₃)/(C₁+C₂+C₃)
D C_eq = C₁ = C₂ = C₃
Correct Answer

Option B is the correct answer.

Detailed Explanation

For capacitors in series, the reciprocal of the equivalent capacitance is the sum of the reciprocals: 1/C_eq = Σ(1/C_i).

Hint

Same formula as parallel resistors.
