Infinite resistor network is shown below, composed of resistors of resistance R0 on the horizontal lines, and 2R0 on the vertical lines.
a) Draw a simplified version of the given network that will enable you to compute the equivalent resistance (Req).
b) What is the equivalent resistance Req, in terms of of R0.
c) Assume the current coming into the network is i0, what is the current i1, that comes out of the first T-junction, and into the horizontal line?
d) What is the current iN, coming out of the Nth T-junction, and into the horizontal line?
