Explanation of Solution

Given:

The range of voltage is 0.00 V − 10.0 V.

Table found in part (a) is attached below:

    Voltage, V Current , I Resistance, R=VI
    20.0140143
    40.0270148
    60.0400150
    80.0520154
    100.0630159
    -2.0-0.0140143
    -4.0-0.0280143
    -6.0-0.0390154
    -8.0-0.0510157
    -10.0-0.0620161

Calculation:

The ohm’s law holds for the device having constant resistance independent of the potential difference.

It is to note that for different voltage the resistance of the nichrome wire is different. This means, that nichrome wire doesn’t obey ohms law.

The resistance is 143 Ω for the voltage from -2.00 V to -4.00 V.

Conclusion:

Hence, the ohm’s law holds for the voltage range of -2.00 V to -4.00 V.
