A big part of your problem is that the approach you are taking is to just memorize formulas instead of understanding what those formulas mean, where they came from, or how to manipulate them to solve types of problems you haven't seen before. This thread is a shining example of that. You were asked by a few folks to post some attempt so that we could help you along the path of discovering how to arrive at what you want starting from what you know. But you wouldn't do that. Instead, you just waited and hoped that eventually someone would just spoon feed you an answer so that you could "make a note" of their final formula. Not a recipe for learning or long-term success.That’s great, so that would work then as long as you know one resistor and the total resistance you can use the calculation to find the other resistors. I’m not sure why that’s not covered in the text book I have. But thank you I’ve made a note of that formula.
I see your point, but I’ve never come across the formula that was presented from other users. So I did make a note of it. I then on my own worked step by step to then understand how they had done it, and got the numbers. I then worked out a number of problems on my own.A big part of your problem is that the approach you are taking is to just memorize formulas instead of understanding what those formulas mean, where they came from, or how to manipulate them to solve types of problems you haven't seen before.

If you want to remove the thread if it makes you feel better. Even when you do ohms law your given a calculation to use. It’s the same with this. I wasn’t expecting the answer rather an explication of how you would work or out. I then took note of how it was done then broke the equasion down and then I was able to do a similar question. Sometimes it takes someone to say have you tried this or that. As it’s something I’ve not come across, so I was greatful for the help and advice.A big part of your problem is that the approach you are taking is to just memorize formulas instead of understanding what those formulas mean, where they came from, or how to manipulate them to solve types of problems you haven't seen before.

Hi DrewStupid,
Your answer of both resistors having a value of 160 ohms is only one of an infinite number of valid answers . (It has not been said that the two resistors have to be the same value.) values of 320 ohms and 106.67 ohms would be another valid answer. Another would be one was 80 ohms and the other infinity.

I think the thing that you're missing is that it's not a matter of whether you've ever seen a particular formula before, but whether you have learned the concepts well enough to be able to take what you HAVE seen before and DERIVE a formula that you've never seen before. If, instead, you have to wait for someone else to show you a new formula, then you are not operating at the level of comprehension that you should be (in a case like this -- certainly not always the case).I see your point, but I’ve never come across the formula that was presented from other users.

Why does this interest me. If you wire a star/delta starter your ohm readings should corrulate between 3-phases. L1 L2 L3 before energizing .Look at my user Name ! Only participating.

I may have missed a major concept and I will be the first to admit my algebra skills are not the best. I did attempt the question before posting it on here.

Presumably you know how to calculate the equivalent resistance of two resistors in parallel given the values of the two resistors. It shouldn't be a completely new problem to then be asked how to calculate the value of one of the resistors given the equivalent resistors and the value of the other resistor. If it is, then you've either missed a major conceptual understanding or have particularly weak algebra skills (both are pretty common). So THAT's the area(s) you really need to try to bolster up, and just adding a new formula to you sheet of formulas is not going to help you get there.
It all bores down to basic education. .....remember there is a contenent called Africa !

You must have been a strict parent or still are !@rdb1 You have been given very specific information. You’re very lucky. This sub forum is titled “Homework Help”. It’s not titled “Homework Done for You”.
Part of that information was the equation to calculate the resistor values for two OR MORE resistors in parallel. Re-read post #19.
So, after re-reading the post, what do you think is the answer to your question?
Who said it was only for rocet scientests?On the lighter side. Is this forum only for rocet scientests ?
No need to remove the thread. The hope is that you not only get help on this particular problem, but also that you perhaps learn something about learning. That's a skill that few people innately know enough about and that nearly everyone never knows enough (most definitely myself included). Similarly, we all have weakness in one area or another. When such an area is identified, we need to see it for what it is -- a weakness that now we have an opportunity to address. Similarly with missing major concepts -- that happens to everyone as they learn things. But we can't learn that major concept until we can at least identify what it is.I may have missed a major concept and I will be the first to admit my algebra skills are not the best. I did attempt the question before posting it on here. As I said you can remove the thread of you want.
My children, now grown up, may have thought I was strict. But as an educator, I may be strict but you’ll know your stuff, if you want to.You must have been a strict parent or still are !
