How do I calculate the equivalence capacitance of this circuit?

In summary, the conversation was about calculating the equivalence capacitance of a circuit with C1 = 8.65 μF, C2 = 4.00 μF, C3 = 8.55 μF, C4 = 3.20 μF. The student attempted to solve the problem by trying different ways to arrange the capacitors, but was unsure due to lack of instruction from the professor. The conversation ended with a request for a circuit diagram.

Calculate the equivalence capacitance of the circuit shown in the diagram above; where C1 = 8.65 μF, C2 = 4.00 μF, C3 = 8.55 μF, C4 = 3.20 μF.


Homework Equations



Capacitance in a series: 1/Ctot = Ʃ(1/C)

Capacitance in parallel: Ctot = ƩC

The Attempt at a Solution



Well, I attempted multiple ways to order each capacitor into a way to solve a formula. In my sixth attempt I presumed that C1 and C2 are in a series and are parallel to C3. I also believe C4 is parallel to C3, so here is my equation:

C = (1/C1 + 1/C2) + C3 + C4

Another idea that came into ferment was the concept of thinking that C2 and C3 are in series and are parallel to C1. C4 would be parallel to C2 and C3 so:

C = C1 + (1/C2 + 1/C3) + C4

I could go on, but since my professor never went over this I am thoroughly confused.

I can not open the link. It is not safe.

Anyway, the equation you wrote "C = (1/C1 + 1/C2) + C3 + C4" is wrong.
The resultant of the series capacitors is 1/(1/C1+1/C2).

What is capacitance?

Capacitance is the ability of a component or network to store electrical energy in the form of an electric charge.

What is a network in the context of capacitance?

In the context of capacitance, a network refers to a collection of interconnected components, such as resistors, capacitors, and inductors, that work together to provide a desired electrical function.

How is capacitance measured in a network?

Capacitance is measured in a network using a device called a capacitance meter, which is typically a handheld device that measures the amount of charge a component or network can hold at a given voltage.

What factors affect capacitance in a network?

The capacitance in a network is affected by several factors, including the material used for the components, the distance between the components, and the voltage applied to the network.

Why is capacitance important in network design?

Capacitance plays a crucial role in network design as it allows for the control and manipulation of electrical signals. It helps in filtering, tuning, and storing electrical energy, making it an essential concept in the design of various electronic systems and devices.
