Find the equivalent resistance across Rab
Parallel Req=(R1 * R2 *...Rn) / (R1 + R2 +...Rn)
The Attempt at a Solution
its the geometry that is throwing me off in this problem.
Starting on the left side,
I want to put 45 & 15 in series, then put that eq. resistance in parallel with the 40ohms and then that total resistance in series with the 6ohms, but I don't know what to do with the 1.5 by node A.
Same thing for the right side, 3 & 5 in series, then that in parallel with 12, that in series with 5.2, but then that in series with 1ohm by node B?
And then do I sum both of those Req's for the total Resistance across AB?
The 2nd problem.. I dont even know where to begin.
