Question

name two metal for which resistance increase with increase in pressure

Answer 1

 Changes in resistivity versus pressure are described by a parameter called the "pressure coefficient of electrical resistance". Most metals have a negative pressure coefficient - i.e., their electrical resistivity decreases with increasing pressure.

However, there are some "anomalous" metals that show a positive increase versus pressure. These include Lithium, Calcium, Strontium, Barium, Bismuth and Antimony. It is thought that the increase in the electrical resistance
versus pressure in these metals may be related to changes in the electron energy structure resulting in changing overlaps between various energy bands.
