Equivalent Capacitance of a set of Capacitors

Click For Summary
SUMMARY

The discussion focuses on calculating the equivalent capacitance of a set of capacitors using the formula for capacitors in series and parallel. The user successfully applies the series capacitance formula, 1/Ceq = 1/C1 + 1/C2, to find the equivalent capacitance of capacitors C1, C2, and C3. The calculations yield an equivalent capacitance of 3.42C after combining the results from both series and parallel configurations. The user expresses confusion regarding the series circuit arrangement, prompting a clarification on the distinction between series and parallel capacitor equations.

PREREQUISITES

Homework Equations



1/Ceq= 1/C1 + 1/C2

The Attempt at a Solution



1/C13eq= 1/3C1 + 1/5C3 = 8C/3 = 2.67C

1/C12eq= (3C x C)/(3C + C) = 0.75C

Ceqtotal = 2.67C + 0.75C = 3.42C

I think the series circuit is throwing me off?

Consider the combination of C2 and C3 as a single capacitor in series with C1.

1/Ceq= 1/C1 + 1/C2


That's the equation for caps in series. What about the equation for caps in parallel?
