The values of current (\(I\)) flowing in a given resistor for the corresponding values of potential difference (\(V\)) across the resistor are given below –
I (amperes) | 0.5 | 1.0 | 2.0 | 3.0 | 4.0 |
V (volts) | 1.6 | 3.4 | 6.7 | 10.2 | 13.2 |
Plot a graph between \(V\) and \(I\) and calculate the resistance of that resistor.
On taking slope for specific points, the formula is
