# Why do the capacitors in this circuit have the same voltage?

C = Q/V

## The Attempt at a Solution

I understand that capacitors in parallel have the same voltage, but wouldn't they be in series after the switch is flipped, since no current goes to the left most portion of the circuit.

They are in both series and parallel.

They are in both series and parallel.
Okay I guess that makes sense.

Doesn't actually matter if you call it series or parallel.Voltage is always relative (eg it's always measured between two points). Both capacitors are connected to the same two points so must have same voltage.

Ah, I get it, that makes more sense. Thank you.
