For a network of twelve resistors shown below, each with a resistance of R, calculate the equivalent resistance between points a and b in terms of R. You need to explain your reasoning and show your detailed work [Hintz since the network is neither series nor parallel, you cannot use the series/parallel combination formulas. Use symmetry considerations instead and assume that [in = out = I]. 12 Resistor Network I (24* : REquivalent _' f:> >~/vw-> IIW \
