A wire of resistance of 20Ω is cut into two equal pieces, how will its resistance and resistivity change?

Expert Answer:

Resistivity is material property. It will not change by cutting the wire.
 
Resistance of wire is directly proportional to length of wire.
Hence when a wire of resistance 200 Ω is cut into two equal pieces ,
then its resistance of each piece of wire will be 100 Ω
