Offer point-of-care and PT/INR self-testing for greater confidence in patient adherence and outcomes Studies have shown that both in-office monitoring and patient self-testing with CoaguChekÂ® systems can help you personalize warfarin therapy, so patients spend more time in therapeutic range1,2.
Electrical resistivity is a property of materials and is different from electrical resistance which is a property of a component. Resistivity is also known as Specific Electrical Resistance or Volume Resistivity. Resistivity can also be defined as the inverse of the conductivity of a material - Ï = 1 / Ï.It is a measure of how a material opposes the flow of electric current. The SI unit of resistivity is ohm meter (Ï.m).
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).
