A rectangular carbon block has dimensions 1.0 cm × 1.0 cm ×...
Between two square faces the area is 0.01×0.01=1×10−4m2 and length is 0.5m. So, the resistance is (3.5×10−5×0.5)/(1×10-4)=0.175ohm, this can be written as, (35/2) x10-2 ohm
Between the rectangular face the area is 0.01×0.5=0.005m2 and the length is 0.01m, hence the resistance is (3.5×10−5×0.01)/0.005=7×10-5 ohm
Between the rectangular face the area is 0.01×0.5=0.005m2 and the length is 0.01m, hence the resistance is (3.5×10−5×0.01)/0.005=7×10-5 ohm
