What is voltage?

Explanation:
Voltage is the difference in electric potential between two points. This potential difference provides the “push” that moves charges through a circuit when a path is available, so current flows. It’s what a battery supplies between its terminals and is measured in volts. It’s not the rate of charge flow (that’s current), not the total energy stored, and not the magnetic field. The idea can be thought of as energy per unit charge available to do work as charges move from high to low potential.
