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

Click For Summary

Homework Help Overview

The discussion revolves around the behavior of capacitors in a circuit, specifically addressing the voltage across capacitors when a switch is flipped. The subject area includes concepts of circuit theory, particularly focusing on the arrangement of capacitors and their voltage relationships.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the arrangement of capacitors, questioning whether they are in series or parallel after a switch is activated. Some express confusion about the implications of this arrangement on voltage.

Discussion Status

Participants are engaging in a productive dialogue, with some clarifying that the voltage across both capacitors remains the same due to their connection to the same two points, regardless of their series or parallel classification. There is an acknowledgment of differing perspectives on the arrangement.

Contextual Notes

There is a discussion about the definitions of series and parallel configurations, as well as the implications of these definitions on voltage measurement in the circuit. Some participants note that the terminology may not significantly affect the understanding of voltage in this context.

Homework Equations


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.

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.
