Homework Help Overview

The discussion revolves around calculating the voltage across capacitors connected in series, specifically focusing on the relationship between charge, capacitance, and voltage in this configuration.

Discussion Character

  • Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants explore the formula for voltage across a capacitor and how it applies to capacitors in series. Questions are raised about the voltage distribution when capacitors are connected in series versus parallel.

Discussion Status

Some participants have provided guidance on the principles governing capacitors in series, noting that the charge remains constant across both capacitors and that the sum of the voltages equals the source voltage. Multiple interpretations of the problem are being explored.

Contextual Notes

There is a mention of specific charge values for the capacitors and a source voltage, but the implications of these values in the context of the series configuration are still under discussion.

What is the formula for finding the voltage across a capacitor?
 
Physics news on Phys.org
[tex]V=\frac{Q}{C}[/tex]

where V is voltage, Q is the charge, and C is the capacitance.
 
Umm, if I have two in capacitors (5E-6 C and 15E-6 C) in series, and the source voltage is 15V, what would the voltage across the first one be?

I know in parallel it would be 15, but how would you do it if they were in series?
 
in series...the charge on both capacitors is the same n the sum of voltages across the 2=source voltage...now work it out
