EXAMPLE 153 Eleven equal wires each of resistance r form the edges of an incomplete cube Find the total resistance from one end of the vacant edge of the cube to the other the other Solution Let A and B be the vacant edges of the cube Let an emf applied across AB send a current 2x in the circuit Since the paths AD and AE are symme trical the current 2x at A is divided into two equal parts x and x At other points the current is divided as shown in Fig 3 164 so that again the currents combine at B to give current 2x Let R be the total resistance of the cube between A and B ni gniwoli tnsmus sil H 2 x y Chto sonatai 2910s sales to sounterest sell hidrosa yu S y nghs an E A noitonj x y si lo vilsmmx di D yi 1 ni mwore as od wuditiay ng X x y 150119 F HA G x y adus ont to Crisq falisisq
