Req of n resistors in series = R1 + R2 + ... + Rn
Req of n resistors in parallel = 1/R1 + 1/R2 + ... + 1/Rn
The Attempt at a Solution
The answer is supposed to be 10 ohms. However, I don't know how they got that.
What I was thinking that some of the resistors short circuit and the current does not pass through them. So, it would be like: 3 ohms, then 6 ohms and finally 5 ohms. However, that adds up to 14 ohms and also I'm very sure that's wrong.
Thanks a lot!
