R1 r2

[varilite]

Why is the value of r1plus r2 a quarter of the end to end resistances added together in a ring circuit

 

[telectrix]

r1 +r2 is end to end, so mid point will be half, but now you have 2 conductors in parallel, so it's half again to get R1+R2. i.e. divide by 4.

As above ^^^^^^^

doing someones homework again i see...

Can none of these "new" sparks read and understand testing. If you are struggling with this the. I would start reading more cause it only gets harder

 

[Guitarist]

Just read up on resistances in parallel.

Reading The title of the book is more than enough for me
