Homework Statement


The attached file has a circuit reduction which I can understand all but the missing capacitance C between B' and C' to the ground each from figure (a) in figure (b)


Homework Equations


N/A

The Attempt at a Solution


Shouldn't there be another capacitance of 2C in the bottom line of figure (b)?

Looks like the voltage sources have been suppressed (Thevenin?). Thus B' and C' both are grounded through the shorted supplies. Both ends of those two caps are thus grounded... and they disappear in a puff of logic :smile:

oh wow. i feel a little embarrassed now but never thought i would make that out in my head. thanks so much!

No problem. Glad to help.

It seems like it was omitted in the reduction process. If that is the case, then the total capacitance between B' and C' would be 3C. It is important to carefully check all components and connections when reducing a circuit to ensure that no components are accidentally omitted.
 

Related to A little circuit reduction question

1. How does circuit reduction work?

Circuit reduction is a method used in circuit design to simplify complex circuits by reducing the number of components or simplifying the connections between components. This is often done to reduce the overall cost, size, or complexity of a circuit.

2. What are the benefits of circuit reduction?

Circuit reduction can provide several benefits, including cost savings, improved efficiency, and reduced complexity. It can also make troubleshooting and maintenance easier, as well as increase the reliability and lifespan of a circuit.

3. What types of circuits can benefit from reduction?

Any type of circuit, from simple to complex, can potentially benefit from circuit reduction. However, it is most commonly used in large, complex circuits, such as those found in computer systems or telecommunications networks.

4. What are some common techniques used in circuit reduction?

Some common techniques used in circuit reduction include simplifying parallel and series connections, eliminating unnecessary components, and combining similar components into one. Another technique is using integrated circuits, which can combine multiple components into one chip.

5. Are there any limitations or drawbacks to circuit reduction?

While circuit reduction can provide many benefits, there are also some limitations and drawbacks to consider. For example, reducing a circuit too much can lead to decreased performance or functionality. Additionally, some circuits may not be suitable for reduction due to their unique design or purpose.
