What Is Electricity?
Understand electric charge, current and circuits without the jargon.
Electricity involves electric charge and its movement or effects. In a circuit, a source can create conditions that allow current to flow through connected components.
How it works
- Voltage represents an electrical potential difference.
- Current describes the flow of electric charge.
- Resistance opposes current in a circuit.
- A complete circuit provides a path for current.
Key takeaway: Voltage, current and resistance describe different parts of what happens in an electrical circuit.
