The depicted graph illustrates the correlation between the potential difference across a metal conductor and the current flowing through the conductor under constant temperature.
The graph has current in amps on the horizontal axis and potential difference in voltage on the vertical axis. A linear line with a positive slope begins at the origin and passes through the points (0.2, 2.0), (0.4, 4.0), (0.6, 6.0), and (0.8, 8.0).
Applying the formula, what is the resistance of the conductor?
Resistance = Potential Difference (Voltage) / Current
To calculate the resistance of the conductor, we can use the formula:
Resistance = Potential Difference / Current
We can take any point on the graph to calculate the resistance. Let's take the point (0.4, 4.0) on the graph.
Potential Difference = 4.0 V
Current = 0.4 A
Resistance = 4.0 V / 0.4 A = 10 ohms
Therefore, the resistance of the conductor is 10 ohms.
