We know how to calculate the total resistance of the cylindrical conductor given its length, radius, and resistivity. But how do we calculate the equivalent resistance when the resistivity is not constant? For example, say the resistivity at a particular point at a distance x ...
Geometry
Yes, solving gives HI^2= 792.
