Capacitance and voltage relationship

Click For Summary

Discussion Overview

The discussion revolves around the relationship between capacitance and voltage, particularly in the context of capacitors connected in series. Participants explore how changes in capacitance might affect voltage under different conditions.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions whether an increase in capacitance necessarily leads to a decrease in voltage.
  • Another participant notes that if the charge on the capacitor remains constant, the voltage will decrease according to the formula V = Q/C, but emphasizes that the outcome depends on the circuit configuration.
  • A later reply highlights the ambiguity in the original question, suggesting that additional context is needed regarding what type of voltage is being referred to, such as safe working voltage, voltage drop, or voltage relative to ground.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as multiple interpretations of the relationship between capacitance and voltage are presented, and the discussion remains unresolved.

Contextual Notes

Limitations include the lack of specific circuit details and the need for clarification on the type of voltage being discussed.

Does an increase in Capacitance mean a decrease in voltage?
Thanks!

If the charge on the capacitor doesn't change the voltage will decrease. (V = Q/C). If it does change it depends on the circuit and what you do to it.

Thanks!

Even adding that they are in series isn't enough information.

You could mean:

The safe working voltage
The voltage drop through them
The voltage between the ends and ground
or??
