A difference in what causes electrons to flow in a circuit?

Voltage, the electrical pressure that pushes current.

  1. Capacitance
  2. Voltage ✔
  3. Inductance

Why: Voltage is like water pressure in a hose. A difference in voltage between two points pushes electrons through the circuit.

Huh, didn't know that: The volt is named for Alessandro Volta, who built the first electric battery around 1800.

The dad joke
Why did the battery feel so confident? It had a positive outlook and plenty of potential.
