3 capcitors (series? parallel?) i cant tell

In summary, the conversation discusses how to combine three capacitors into one equivalent capacitor. The solution involves redrawing the schematic and realizing that all three capacitors are in parallel.

Homework Statement


This isn't really a homework question but I figured this would be the best place to post it. Say I had three capacitors like this picture below, I need to combine them into one equivalent capacitor.

The Attempt at a Solution



I BELIEVE that C1 and C2 are in parallel, and then after I add those together, I can solve for that one and C3 in parallel... but I'm not 100% sure. Any help appreciated!

It's obvious how the caps are connected if you redraw the schematic so that all the terminals which are eventually connected to the same line (i.e., at equipotential) go to a single point.

oh! so all 3 are parallel then. right?

Bingo.
 

FAQ: 3 capcitors (series? parallel?) i cant tell

What is the difference between capacitors in series and parallel?

Capacitors in series have a combined capacitance that is less than any of the individual capacitors, while capacitors in parallel have a combined capacitance that is equal to the sum of the individual capacitors.

How do I determine if capacitors are in series or parallel?

If the capacitors have a common node or connection point between them, they are in parallel. If they are connected end-to-end, they are in series.

What happens to the voltage across capacitors in series or parallel?

In series, the voltage across each capacitor is divided proportionally based on their capacitance. In parallel, the voltage across each capacitor is equal.

Do the capacitors in series or parallel share the same charge?

In series, the capacitors share the same charge. In parallel, each capacitor has its own separate charge.

Which arrangement is better for increasing the total capacitance of a circuit?

For increasing the total capacitance, a parallel arrangement is better since the individual capacitances are added together. In series, the total capacitance is decreased.
