Grade 11 physics and equivalent resistance

Click For Summary
SUMMARY

The discussion centers on calculating equivalent resistance in a circuit, where a participant initially calculated 45.3 ohms but later confirmed the correct value as 25.6 ohms. The discrepancy arose from not properly identifying components in series and parallel configurations. The correct calculation emphasizes the importance of methodical analysis in circuit problems, leading to a precise result of 25.555 ohms.

i keep getting 45.3 ohms but the answer is 25.6 ohms

Can't tell where your mistake is unless you post your intermediate steps that lead you to a (false) answer of 45.3 ohms, but I did it my self and I found it to be 25.6 ohms indeed (25.555 to be more precise).

Yes I figured it out I wasn't using my common sense, thank you

Not exactly common sense, but it is kind of easy problem if you carefully identify the components in series and the components in parallel.
