How To Find Resistivity Of A Wire

how to find resistivity of a wire

TO MEASURE THE RESIS TIVITY OF THE MATERI AL OF A WIRE

The resistance of a wire will prevent the amount of electric current from flowing through the wire (Conductor) maximally. The lower the resistance of a wire, the more the amount of electric current can flow through the wire.
