For a certain wire kept at constant temperature the following observations were recorded.
Potential difference V (V)
Current I (A)
2
0.40
5
1.00
Using only the two given readings, answer the following.
(a) Plot a graph of I (along y-axis) versus V (along x-axis) on a suitable scale.
(b) From the graph determine the resistance of the wire.
(c) Using the same graph, estimate the current that would flow through the wire when the applied potential difference is 8V.
