Two identical capacitors are arranged in a circuit. What is the ratio of the equivalent capacitance of the circuit when the capacitors are in series to when they are in parallel?
Answer (2)
Ceq in series is calculated by 1/C1 + 1/C2 + .... While, in parallel, Ceq= C1 + C2 + ...
So the ratio is 1/Ceq = Ceq
The ratio of the equivalent capacitance of two identical capacitors in series to that in parallel is 4 1 . In series, the equivalent capacitance is half the single capacitor's capacitance, while in parallel it is double. Therefore, the final ratio is derived as 4 1 .
