This is when the symptoms of mild spinal stenosis are felt, such as occasional back pain, neck pain and leg pain. These symptoms are uncomfortable, but typically do not get in the way of a personâs normal daily activities such as sitting, standing, walking, working, etc.pinal stenosis is a gradual disease that is largely caused by the normal aging process. Over time, age-related conditions like arthritis of the spine, disc degeneration, bulging discs, etc. begin to encroach on the spinal column, causing it to become narrow.
The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor.n object of uniform cross section has a resistance proportional to its resistivity and length and inversely proportional to its cross-sectional area. All materials show some resistance, except for superconductors, which have a resistance of zero.
Electrical conductivity is the ability of a material to carry the flow of an electric current (a flow of electrons).Imagine that you attach the two ends of a battery to a bar of iron and a galvanometer.nother way of describing the conductivity of a material is through resistance. Resistance can be defined as the extent to which a material prevents the flow of electricity. Silver, aluminum, iron and other metals have a low resistance (and a high conductivity).
