Power is the rate at which energy is used, transferred, or converted. It measures how quickly work is done or energy is transferred.
In simpler terms, power tells you how fast something can do work or how much energy is being used or produced per unit of time.
Formula:
The formula for power is:
\[
P = \frac{E}{t}
\]
Where:
SI Unit of Power:
The SI (International System of Units) unit of power is the watt (W).
1 watt (W) is equal to 1 joule per second (J/s).
In other words, if 1 joule of energy is used or produced in 1 second, the power is 1 watt.
So, power is essentially a measure of how much energy is being used or produced over time.

Where:
- \( P \) is the power (in watts, W)
- \( E \) is the energy (in joules, J)
- \( t \) is the time (in seconds, s)
