In a graphical analysis of Ohm's Law, what is plotted on the Y-axis?

In a graphical analysis of Ohm's Law, voltage (V) is typically plotted on the Y-axis, while current (I) is plotted on the X-axis. Ohm's Law states that V = I × R, indicating that voltage is dependent on the current flowing through a conductor and the resistance of that conductor. Therefore, since voltage is influenced by the value of current, it is considered the dependent variable in this relationship.

The choice of plotting the dependent variable on the Y-axis aligns with standard practices in graphing, where the outcome or response variable is displayed vertically. This allows for an effective visual representation of how changes in current (the independent variable) affect the voltage.

Understanding this framework is crucial for analyzing and interpreting electrical circuits and can be applied in various scenarios within electrical engineering and physics contexts.
