To visualize this relationship, you can adhere to these steps: ● Select various electrical resistance values (R). For instance, you can opt for multiple R values, such as 1 Ω, 2 Ω, 3 Ω, and so forth. ● Utilize the aforementioned formula to compute the electrical voltage (V) for each chosen resistance value. For example, if R = 1 Ω, then V = I * 1. If R = 2 Ω, then V = I * 2, and so on. ● Choose diverse current values (I). You can, for instance, select various I values, such as 1 A, 2 A, 3 A, and the like. ● Apply the formula mentioned above to calculate the electrical voltage (V) corresponding to each current value. For instance, if I = 1 A, then V = 1 * R. If I = 2 A, then V = 2 * R,and so forth. ● Create a table with columns denoting the calculated R value, I value, and V value. ● Once you have arranged the data into a table, you can employ graphing software like Microsoft Excel or, if preferred, do it manually to construct a graph. In this graph, the X-axis representsI (current), and the Y-axis represents V (voltage). You can then connect the data points correspondingto each combination of R and I with straight lines. This graph will effectively illustrate the linearrelationship between voltage, current, and resistance in accordance with Ohm's Law.
