Potential Difference and Resistance

Potential Difference (also known as Voltage)

Potential difference, also commonly referred to as voltage, is an important concept to understand. In these videos I'm using the rope loop model to explain this.

The current through a component depends on both the resistance of the component and the potential difference across.
