How can I draw a graph showing the relation between voltage (y-axis) and current (x-axis)? Draw
the best fit straight line through the points on your graph. Calculate the slope of this line
as another estimate for R.
Here are my values.
Voltage (v) | Current (A) | V/I |
0.1 | 0.04 | 0.250 X 1000 = 250 Ohm |
0.57 | 2.5 | 0.228 x 1000 = 228 Ohm |
1.54 | 6.8 | 0.226 x 1000 = 226 Ohm |
2.75 | 12.3 | 0.223 x 1000 = 223 Ohm |
3.68 | 16.4 | 0.224 x 1000 = 224 Ohm |
4.73 | 21.1 | 0.224 x 1000 = 224 Ohm |
4.95 | 22.0 | 0.225 x 1000 = 225 Ohm |
5.07 | 22.6 | 0.224 x 1000 = 224 Ohm |
5.3 | 23.6 | 0.224 x 1000 = 225 Ohm |
5.8 | 26.0 | 0.223 x 1000 = 223 Ohm |
Average: 227 Ohm |
