# Relationship between resistance to length and radius

### Copper and electricity. Resistance and resisitivty.

Resistance is inversely proportional to cross sectional area. given constant resistivity, length, and temperature, the resistance of Then, since the diameter of a conductor is twice its radius, we can write It's called an inverse square law relationship, and if I may wax philosophical for a moment, it's one of. We did an experiment using resistance putty and a multimeter. We changed the radius of the putty but kept the length the same. We recorded. The electrical resistance of a circuit component or device is defined as the ratio of the voltage applied to density is maximum at the maximum radius of the wire and drops for smaller radii within the wire. Resistance = resistivity x length/area .
