Hello, all, and then there's that circuit topology problem found in some
circuit theory textbooks:
There is an infinite planar square lattice of connected 1-ohm resistors
that extends to infinity in all directions. A DC ohmmeter placed across
any resistor would register what value? The answer is 0.5 ohm but how do
you go about solving for it? (Hint: There is an easy way and a much more
difficult (general) way to attack this problem. This problem is a discrete
example that in the limit would indicate the distribution of a DC electric
field (and currents) in a conducting, isotropic metal plate as one moves
away from the source of excitation. Sincerely, and 73s from N4GGO,
