an experiment is conducted to measure the electrical resistivity of nichrome in the form of wires with different lengths and cross-sectional areas. for one set of measurements, a student uses 30-gauge wire, which has a cross- sectional area of 7.30 10-8 m2. the student measures the potential difference across the wire and the current in the wire with a voltmeter and an ammeter, respectively.
