Cables in parallel

[static zap]

Buy a cheap meter and try the practical approach,Maplins resistors !

 

[hsharp]

Sorry yes it is insulation.
The question is a C&G word for word.

 

[Silly Sausage]

Have you sussed the answer yet?

 

[Sintra]

Work it out what is the total resistance of 200 M ohms and 20 M ohms in parallel. This will answer your question.

 

[Richard Burns]

When working this out remember that you are measuring resistances in parallel.

The total resistance of resistors in parallel is XXXXer than the XXXXest?

 

[Silly Sausage]

Too many Xs there Rich!

 

[Richard Burns]

I am trying to be obtuse:ninja:, but I shouldn't have used four I should have used seven or something.:tongue3:

 

[Baker1988]

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

 

[hsharp]

the answer is a then

 

[Baker1988]

the answer is a then

Try again

 

[Sintra]

the answer is a then

Show your working out then please. Then we can assist from there.

 

[hsharp]

is it B, I am just learning

 

[Richard Burns]

one more go!

 

[Baker1988]

Show us your working out mate I'll give u a clue the answer starts with one of the first 4 letters of the alphabet

 

[hsharp]

what d

 

[Richard Burns]

OHhhh! last chance!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[Sintra]

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.

 

[Baker1988]

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

 

[Richard Burns]

parallel resistors

total resistance of resistors in parallel is lower than the lowest individual value

It really is worrying when the questions are multi choice, yet people still try and randomly guess rather than at least attempt to make a educated guess.
