The resistance from A to B is 6 kΩ.

 

The resistance from A to B is 6 kΩ.

Thanks. I Kept getting answers that would round to 6k also but was told they were wrong

 

The four resistors on the right half are shorted out. So, do not appear in any calculation. The four resistors on the left half are straightforward. 6K ohms is correct. BTW, there is no rounding required.

(10K || 10K + 10K) || 10K = 6K "||" means "in parallel".

 

Is this post in the wrong topic? Maybe one under Hardware Design?

 

Or homework?

Thanks for explaining! And sorry if I put this in the wrong category

Actually with this equation you gave I keep getting 4K so now what am I doing wrong?
because(10K || 10K + 10K)=6.6repeating then 6.6K || 10K= 4K ?

 

Take it step by step. The right group is shorted out, so forget about them. In the left group, the diagonal resistor is in parallel with the lower resistor. 10K || 10K = 5K.
That 5K is in series with the top 10K. 10K + 5K = 15K. That 15K is in parallel with the input 10K, so 10K || 15K = 6K.

Thanks for your help!

(10K || 10K) is 5K. Then, 5K + 10K is 15K. Then 15K || 10K is 6K.

R1 || R2 = (R1*R2)/(R1+R2)

It looks like you are calculating 10K || (10K + 5K). The order of operation is (10K || 10K) + 10K.

 

Working through all the parallel and series combinations I get 6.33k I worked it out from the back ending with the final parallel pair which is 17.27k ll 10k which is 6.33k

(10k+ 10k) ll 10k
then Bunch of series ... I take it back the back end is shorted. Haha.. it’s 6k
