Square of resistors within a circuit. What is the equivalent

Click For Summary
SUMMARY

The discussion focuses on calculating the equivalent resistance of a square configuration of resistors within an electrical circuit. Participants emphasize the importance of maintaining connections while rearranging circuit components, specifically referencing the Y-Δ transform as a critical method for simplifying complex resistor networks. The original question involves three interconnected resistors, and confusion arises regarding the introduction of an intersecting node in the solution. The Y-Δ transform is highlighted as a necessary tool for resolving this issue.

PREREQUISITES
  • Understanding of basic electrical circuit theory
  • Familiarity with resistor configurations and their properties

Homework Equations


-We can re-arrange circuit components into simpler orientations as long as the components' connections to previous nodes are maintained.

The Attempt at a Solution


-I attempted to re-arrange the loop of three resistors at the upper left region to no avail. Where did that intersecting node in the solution come from? There is no such node in the original question, where all three resistors are connected.
