Cables in parallel

[hsharp]

A number of cables are tested for installation resistance. The highest individual value is 200M ohm and the lowest is 20Mohm. The measured value, when all cables are connected in parallel, will be?

A. great than 200M
B. 200M
C. Less than 20M
D. The sum of the individual values.

Or

E. prepare to be quizzed on what you think it will be lol

College question?

 

[Sintra]

Is this homework?

Insulation resistance

What do you know of series and parallel circuits with regard resistance values

 

[KAS1]

What was the name of the chap doing the testing???

 

[Guitarist]

Is this homework?

If not, he has a strange hobby

Thought this would be an interesting power problem.

 

[GLENNSPARK]

wheres he gone?
surely he didn`t expect us to just give it to him (the answer that is)...

Should he not get a few brownie points for the title then Tony

I will give him a clue

3 of them answers are looking a bit suspect

Gets on my nerves when people start a thread and then disappear after 10 minutes. :mad2:

Utter laziness not to even have a pop at it and then disappear!

`drop in centre` syndrome again i`m afraid

F. Dump the 20meg cable and put it in storage to dry out for future reference then de-rate your mcb as it was probably oversized anyway.

F a). It's Insulation resistance not Installation

Good Luck.

is it just me or does this question not actually make much sense?

well...you dont post a question..then just f**k off do you....lol..

 

[Stroppy]

Resistances in parallel? Come on, this is second year stuff!!

 

[chrish_1977]

Maybe he has seen the error of his ways and decided to hide

What about if your bypass wire is only a few microns thick?
