Meaning
Power is the rate of Energy Transfer.
About Power
- Power is how quickly energy is transferred from one store into another.
- Energy Transfered is the same as Word Done, so power is also the rate of work done.
Equation
\[Power = \frac{Energy Transferred}{Time}\] \[P = \frac{E}{t}\]
\[Power = \frac{Work Done}{Time}\] \[P = \frac{W}{t}\]
Where:
- P = Power
- E = Energy Transferred = W = Work Done
- t = Time
