EXP-1> TO DETERMINE THE RESISTANCE PER CM OF A GIVEN WIRE BY PLOTTING A GRAPH OF POTENTIAL DIFFERENCE VERSUS CURRENT Materials Required: A Resistance wire, voltmeter, ammeter, battery, rheostat, meter scale, one way key, connecting wires etc. Theory: If I be the current flowing through a conductor & V be the potential difference across its ends, then according to Ohm’s law V∝I or V = RI Where, R is the constant of proportionality. It is known as resistance of the conductor. V/I=R R depends upon the nature of material, temperature & dimensions of the conductor. Procedure: 1. Clean the ends of the connecting wires with the help of sand paper in order to remove any insulating coating on them.

Note whether pointers in milli-ammeter and voltmeter coincide with the zero mark on the measuring scale. If it is not so, adjust the pointer to coincide with the zero mark by adjusting the screw provided near the base of the needle using a screw driver.
