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.

I give up. What's the point in guessing you need to know and understand the formula for resistances in parallel. You need to do a bit of work on this yourself rather than waiting for someone to give it to you on a plate.

Come on mate I can't c why you don't know the answer to this

come on pal if u look at my first post i told you the answer (c instead of see)

in a parellel circuit the total restistance is always lower then the lowest resistor so in this case the lowest is 20m so it will be lower then that.

if you are a trainee apply for the trainee section and we will all try to help you

thats why i like the 2357 that i am on we have no multiple choice questions or tests its all short answers so not as easy

IMO there should be no multi choice exams in this industry.
