Question

A solid metallic cuboid of homogeneous material having geometrical dimension as shown in the figure will have a ratio of resistances for the sense of current along x , y and z directions respectively, equal to, a : b : c, a : c : b, a 2 : b 2 : c 2, a 2 : c 2 : b 2

MARKS App · Accepted Answer

R X = ρ a b c R Y = ρ c a b R Z = ρ b a c R X : R Y : R Z = a b c : c a b : b a c a 2 : c 2 : b 2 (multiply each ratio by a b c )
