Homework Help Overview

The discussion revolves around the concepts of series and parallel circuits, specifically focusing on the behavior of current and voltage across resistors in these configurations. Participants express confusion regarding the relationships between current, potential difference, and potential energy loss in these circuits.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants attempt to clarify whether the current through resistors in series is the same and if the voltage across them is also the same. Questions arise about the implications of voltage being the same in parallel circuits and how that affects current.

Discussion Status

The discussion is ongoing, with participants exploring the foundational rules of series and parallel circuits. Some guidance has been offered regarding the application of Ohm's law to determine voltages and currents in different configurations, but there is no explicit consensus on the interpretations being discussed.

Contextual Notes

There appears to be confusion regarding the definitions and relationships of current and voltage in series versus parallel circuits, with participants questioning their understanding of these concepts.

Homework Statement


I'm a little confused, in a series and parallel circuit, does it make sense if i say that the current through 2 separate resistors is the same but the potential difference is different and also is the amount of potential energy lost?? It's this that's getting me confused with the concept..

The current through two series components is the same. The voltage across two parallel components is the same.

But for the series, does that mean that the voltage is the same for both resistances?
And for the parallel one, if the voltage is the same, does that make the current equal as well?

No and no. If you combine the two rules mentioned by Berkeman with ohms law you can work out what the voltages are for series resistances with a known total voltage across them, or you can work out the currents for parallel resistances with a known total current going through them.
