The resistivity of a material is a measurement of its opposition to an electric current. In an electric circuit, the greater the resistance to the flow of electrons, the weaker the electric current will be. The resistivity of silver is about $1.59\times {10}^{-8}\mathrm{\Omega }\mathit{m}$ at 20 degrees Celsius which means that silver cannot resist the flow of electrons very well.
