Question 1147552: When an electric current flows through a wire, the resistance to flow varies directly as the length and inversely as the cross-sectional area of the wire. If the length of the wire changes by a factor of 1.3, and the diameter of the wire changes by a factor of 2.3, by what factor will the resistance change?

The increased length increases the resistance by a factor of 1.3.

The increased diameter decreases the resistance by a factor of (2.3)^2.

Overall the resistance changes by a factor of (1.3)/(2.3)^2.

Use a calculator to convert that to any required form.
