## General --- - [[Energy]] per time: $\frac{E}{T}$ - ex. cookie has high [[Energy]] but low power (requires lots of time to digest, low amounts of [[Energy]] per second), but dynamite has lower [[Energy]] than cookie but very high power (tons of [[Energy]] expended second, so dangerous) - the rate at which - [[Work]] is done - [[Energy]] is transferred ![[CleanShot 2024-11-13 at [email protected]|400]] ## Units --- - [[Watt]] - [[Horsepower]] ## [[Electricity]] Perspective --- - amount of [[Work]] done per second when [[Electricity]] flows - Power = Voltage * Current - [[Power]] (watts) - [[Voltage]] (volts) - [[Current]] (amperes) - home [[Electricity]] bills are typically charged based on [[Power]] (kilowatts)
