Objective:
To measure the resistance of a given conductor using the slide-wire Wheatstone bridge and to determine the specific resistance or resistivity of the material of the conductor.
Objective:
Measuring the voltage and the current on four constantan wires with different cross-sectional areas. Measuring the voltage and the current on two constantan wires with different lengths. Measuring the voltage and the current on a constantan wire and on a brass wire. Verifying Ohm’s law and determining the resistances.
