Definition
Electric Potential (Voltage) is the electric potential energy per unit charge.
Why It Matters
It is the “electrical pressure” or pump that drives electric charge through conductors, serving as the source of electrical energy distribution.
Core Concepts
- Voltage (): The “electrical pressure” that moves charge. Measured in Volts (V). .
- How to read: “The potential of one volt equals one joule per coulomb.”
- Meaning: Energy available per unit charge—electrical “pressure” that drives current.
- Electric Field Relation: Voltage represents the work done per unit charge moving through an electric field.
