I'm interested in calculating the resistance of an object using the formula: R=ρ (L/(T*W)) where L is the length and T*W is the cross sectional area. My object is however, a wedge, so I do not know exactly how to calculate the resistance without doing an integral: http://imageshack.us/photo/my-images/585/9evf.jpg/ Is this the proper approach? I'm having some trouble with the actual calculation of this... not sure if I'm setting up the problem correctly. Any help would be much appreciated!!
