(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Suggest a reason why theoretical and experimental results for resistors R1 and R2 are different for: experimental R1 and R2 in series vs R1+R2

and Experimental R1 and R2 in parallel vs 1/R1+1/R2

R1=23.080 Ohms

R2=41.289 Ohms

Series Experimental=58.769 Ohms

Series Theoretical=64.369 Ohms

Parallel Experimental=16.846 Ohms

Parallel Theoretical=14.804 Ohms

2. Relevant equations

Parallel: Rs=1/R1+1/R2

Series: Rs=R1+R2

3. The attempt at a solution

Parallel.

In this example as well since the current has to travel through extra wire which makes it a parallel. The wire's resistance adds on to the calculated resistors value.

Series:

The theoretical and experimental values for the resistance are different since the electricity has to travel through extra wire in case 1 and this wire causes resistance which adds to the value of the final resistance measured. The value which is more reliable for measuring the series's resistance is 58.769 Ohms as measued in Part 2

Is this correct^?
