@electricalmath: Can you find the equivalent resistance of this infinite tower? Let’s solve this challenging problem using the “Fundamental Theorem of Engineering”. #electrical #electricalengineering #electronics
ok, i said B cuz it looks like euler number, then check again and it would be harder if one answer would be 2.718

R=2+R/(R+1)
R²+R=2R+2+R
R²-2R+1=3
(R-1)²=3
R=1+√3

i didn’t realize there were levels to this 😣

We use Y and delta transfer here but too lazy to do it some one do it

that reminds me of an infinitely nested equation in algebra! 😂

It can be expressed as a recusive sequence of n elements : An=(An-1 + 2R)||R, where A1=R. This series doesn't take the extra 2R on the edge, so calculating the limit of the sequence and adding 2R at the end - solves the problem.

I used guessing.. but like since its a lot of "almost 1" it made me think of the definition of eulers number and that answer sas close

if its an infinite series of resistors wouldn't that mean that Rxy is approaching 1ohm and that it would reach 1 ohm at infinity so wouldn't a more accurate answer for R total be 2.99999....ohms??
