A 9.0 μF capacitor, a 10 μF capacitor, and a 18 μF capacitor are connected in series.

What is their equivalent capacitance? (answer in μF)

science physics

Answer 1

Answer #1

In series combination

Equivalent capacitance is Ceq

1/Ceq = (1/C1)+(1/C2)+(1/C3)

let C1 = 9 uF

C2 = 10uF

and C3 = 18 uF

then

1/Ceq = (1/9)+(1/10)+(1/18)

Ceq = 3.75 uF
