Suppose you were to build this circuit and take measurements of current through the resistor and voltage across the resistor:
Recording these numerical values in a table, the results look something like this:
Voltage Current
0 0
2 0.5
4 1
6 1.5
8 2
1) Plot graph (Voltage vs. Current) (0.2p)
2) What mathematical relationship do you see between Voltage and Current in this graph? (0.2p)
3) Read Resistance from the graph. (0.2p)
