(c)
whether the nichrome wire obey Ohm’s law or not.
(c)
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, |
2 | 0.0140 | 143 |
4 | 0.0270 | 148 |
6 | 0.0400 | 150 |
8 | 0.0520 | 154 |
10 | 0.0630 | 159 |
-2.0 | -0.0140 | 143 |
-4.0 | -0.0280 | 143 |
-6.0 | -0.0390 | 154 |
-8.0 | -0.0510 | 157 |
-10.0 | -0.0620 | 161 |
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
Conclusion:
Hence, the ohm’s law holds for the voltage range of -2.00 V to -4.00 V.
