i would like to know if there is any advantage. or not?jbriggs444 said:What is the context for this question? What leads you to think that there is an advantage? And what power dissipation are we talking about?

The same total power would be dissipated?
the two gives the same overall capacitance.ZapperZ said:What if you want a capacitor with a really large capacitance, but it doesn't exist? All you have are capacitors with smaller capacitance.
Zz.
so, is there an advantage?jbriggs444 said:An ideal capacitor does not dissipate power. Any energy provided to put charge in is harvested when charge comes out.
If you want to know whether there is an advantage, ask whether there is an advantage. Don't ask what the advantage is.

In what context? i.e. Why do you ask.PhysicStud01 said:the two gives the same overall capacitance.so, is there an advantage?
if i were to choose between the 2 in a practical circuit, which one would be better? and why? or is there no difference?jbriggs444 said:In what context? i.e. Why do you ask.
As idealized circuit elements the two are identical. You know this. So you must be asking about something else. But what?

Please stop asking this question and start recognizing that it is meaningless without context and even then will always contain an element of opinion. "Different" may or may not mean "better", depending on what you want. Learn that as a life lesson and apply it several times a day in various situations. Elevator or stairs? Chicken or steak? Drive or take the train?PhysicStud01 said:if i were to choose between the 2 in a practical circuit, which one would be better? and why? or is there no difference?
You didn't even provide values for the capacitance, but assuming equal total capacitance, the two scenarios are identical. But again: what do you want? What are your constraints? That will dictate design choices.i want to know if there are changes to things like

There are two scenarios that I'm familiar with for splitting up capacitors like that (beyond any power dissipation issues):PhysicStud01 said:Can someone tell me what is the advantage of using the combination instead of a single capacitor?

PhysicStud01 said:i thought maybe it's about the power dissipated?
if current I flows through the single capacitor and the pd is V, power dissipated = VI

Splitting up capacitors is typically done to increase the overall capacitance in a circuit. By connecting multiple capacitors in parallel, the total capacitance is equal to the sum of each individual capacitor's capacitance.
Yes, there are several advantages to splitting up capacitors. One advantage is the increased capacitance, which can improve the performance of the circuit. Additionally, splitting up capacitors can also distribute the load more evenly, reducing the stress on any one capacitor and potentially increasing its lifespan.
To determine the total capacitance when splitting up capacitors, simply add the individual capacitance values of each capacitor that is connected in parallel. For example, if two capacitors with capacitance values of 10μF and 20μF are connected in parallel, the total capacitance would be 30μF.
In theory, capacitors can be split up in any circuit. However, it is important to consider the circuit's design and purpose before making any modifications. Splitting up capacitors may not always provide the desired results and could potentially cause issues in the circuit.
While there are advantages to splitting up capacitors, there are also potential drawbacks. Splitting up capacitors can increase the complexity of a circuit and may require more space. Additionally, if not done properly, it could lead to imbalanced voltages or currents in the circuit, causing malfunctions or damage.
