Help Please with Parallel connection affect on Resistance!

[nazoom]

Hi i have this question that i am not sure of the answer. Can you please Help?


State the effect on measured resistance when cables are connected in parallel.

Answer:

The resistance value will be reduced. For example in resistance for Zs testing in ohms has a measured value that is less than the calculated value used by Ze+(R1+R2). The parallel paths is provided by any extraneous conductive parts.

I have the books OSG, Wiring 17th Edition, and GN3.


Thanx a million.

Sorry lost that ..............as you have posted the answer to your question what is it you need to know

correct, you have answered your own question. the reading will be inaccurate due to parallel resistance according to the formula
R= ( R1xR2)/(R1+R2) where R is your reading, R1 is the true Zs, R2 is the parallel path resistance. Put some values in and see how the result is different
