Detailed Solution

The above statement is True.
An electrical conductor's electrical resistance is a gauge of how challenging it is to send an electric current through that conductor. Electrical conductance, which measures how easily electric current moves, is the inverse quantity. Resistivity is a property of a conductor that prevents the passage of an electric current through it and is independent of the shape and size (length and area) of the materials but is dependent on the composition and temperature of the materials. It is indicated by[241][242] ohm-metre. This is the unit used in the SI system.[243][244]
