Key ideas in The Flow of Power
- Voltage acts as the electrical pressure or push
- Current cannot flow without a potential difference
- Voltage is defined as electric potential energy per unit charge
- Higher voltage means more work can be performed
- Voltage is analogous to pressure in a fluid system
- Current represents the movement of the medium (water or electrons)
- Mapping the water-pipe analogy to electrical components
- The relationship between voltage and potential energy
- Voltage represents the push or pressure in a circuit
- Amperage represents the volume of charge moving past a point
- Amps measure the rate of flow per second
- The Coulomb is the unit for electrical charge
- The conceptual difference between electrical pressure and flow volume
- The definition of an Ampere as a rate of charge per unit of time
- Amperage represents the actual amount of electricity being consumed
- Devices that do more work require a higher volume of charge flow
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives The Flow of Power the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
