Which quantity is defined as electrical pressure pushing current?

Explanation:
Voltage is the electrical pressure that pushes current. It’s the potential difference between two points that provides the driving force for charges to move through a circuit. When voltage is higher (with resistance unchanged), more current flows, illustrating the direct relationship in Ohm’s law: I = V / R. The actual flow of charge is current, while resistance is what opposes that flow, and power is the rate at which energy is delivered (P = V × I). So the pushing force behind current is voltage.
