Calculate Equivalent Resistance in an Equilateral Triangle Electric Circuit

Click For Summary
SUMMARY

The discussion focuses on calculating the equivalent resistance of three 66.0 Ω resistors arranged in an equilateral triangle configuration. Participants emphasize the need to identify series and parallel combinations to determine the equivalent resistance between any two points (AB, BC, AC). The solution involves recognizing the delta configuration of resistors and applying the appropriate formulas for series and parallel resistances. The consensus is that a combination of series and parallel calculations is necessary to arrive at the correct equivalent resistance.

Homework Statement


Three 66.0 Ω resistors are connected across the sides of an equilateral triangle ABC as shown in the figure.
What is the equivalent resistance between any two points AB, BC, AC of this circuit?



Homework Equations





The Attempt at a Solution


I don't understand. They give me a triangle with the same resistance at each point, and there asking for the resistance between any of the two points

Do you see any series or parallel combinations you could make?

Series

Well, make them! What problems are you having? Show some work and ask questions.
 
I can't show any work because I don't understand what I am being asked to find. If there series, to find the equivalent resistance you just add them because there series

you need to find the equivalent resistance by making one series and one parallel combination (after the series one).
 
Is this a delta of resistors by chance? Something like: /_\ with a resistor on each wire of the delta?
