We recently did a Resistance in Circuits lab.(adsbygoogle = window.adsbygoogle || []).push({});

My coded resistances were

33, 100 and 220.

The measured resistance was

33.3, 101.6 and 219

So we did 3 setups. (Series, Parallel and Combination)

Series = 351.8 measured ohms

Parallel = 22.5 measured ohms

Combinations = 101.5 measured ohms

The links below are scanned images of my work.

I am confused on what i am comparing.

I find the calculated Req with the uncertainty... so I am comparing that to the measured, but i am confused on what to do with the uncertainty.

I need to find the discrepancy and say if it is signi. or insigni.

For Parallel i found, 22.5 -22.3 = 0.2 and the error was 0.141

So its Sig. But the rest confused me.

I hope someone can help me understand.

thanks in advance.
