In the context of an experiment demonstrating the relationship between current and potential difference (p.d.) in an electrolyte, it is standard practice to plot current (I) on the Y-axis. This convention aligns with the formula V = IR, where voltage (V) is the product of current and resistance (R). While some may assume that the slope of a graph must equal a constant, this is not a strict rule; it is a matter of convenience. Additionally, conductance (G), defined as the reciprocal of resistance, can be expressed as I = V*G, further supporting the choice of plotting current on the Y-axis.
PREREQUISITESStudents and educators in physics, electrical engineers, and anyone conducting experiments related to current and voltage in electrolytic solutions.
Darth Frodo said:In an experiment to demonstarte relationship between current and p.d. in an electrilyte the book says to plot current on the Y axis. Why is this?
V = IR
R = V/I
I always assumed when you plot graphs, the slope must equal the constant.
Any input appreciated.
