Homework Help Overview

The discussion revolves around a circuit analysis problem involving resistors that appear to be in series but are claimed to be in parallel. Participants are seeking clarification on the definitions and visual representations of parallel resistors in electrical circuits.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the definition of "parallel" in the context of circuit design and how it applies to the given configuration of resistors. There is an exploration of how visual representation can affect understanding, with some suggesting that the circuit can be redrawn for clarity.

Discussion Status

The discussion is ongoing, with participants providing insights into the nature of parallel resistors and how they can be represented differently in diagrams. Some guidance has been offered regarding the conditions under which resistors are considered parallel, but there is no explicit consensus yet.

Contextual Notes

Participants are navigating potential confusion caused by the circuit's drawing style, which may not align with traditional representations of parallel circuits. There is an acknowledgment of the challenge in interpreting circuit diagrams accurately.

In this circuit, please tell me how they got the 4 ohms and the 12 ohms in parrallel when they look like they are in series


Please help me i am so desperate for an answer!

What definition of "parallel" are you using?
 
As in resistors are in parrallel and they use the formula 1/Req= 1/R1+...Lewando trust me its very confusing
 
I know that circuits can be drawn to confuse intentionally-- the trick is to spot when this is happening. When resistors are "in parallel" they don't need to be drawn both vertically or horizontally-- as in your case they are drawn perpendicularly. But you should realize that you can redraw the circuit so they are literally parallel without changing any functional aspect of the circuit.

How about this unofficial definition: if there are 2 nodes, A and B with one resistor between them, then you place yet another resistor between them, those two resistors are "in parallel".

Your example shows exactly that.
