Answer:
Explanation:
A currentvoltage characteristic or IV curve (currentvoltage curve) is a relationship, typically represented as a chart or graph, between the electric current through a circuit, device, or material, and the corresponding voltage, or potential difference across it.
In the graph, the voltage is plotted along the y-axis and the current is plotted along the x-axis. In the given example, the current I against the potential difference V, is a straight line with constant slope 1/R as the relation is linear and ohmic. That is, the remains constant for varying values of voltage and current.
The resistance can be found using the ohm's law which states R=V/I=0.5/0.2 or1.0/0.4, etc will give 2.5 ohms.
Hence, the resistance is 2.5 ohms.
