Power

Power is mathematically defined as the work done or energy transferred or converted per unit of time. The standard unit of power is the watt (W), named after the Scottish engineer James Watt, who played a critical role in the development of the steam engine during the Industrial Revolution. One watt is equivalent to one joule of work done or energy transferred in one second.
Mathematically, power (P) is expressed as:
Power (P) = Work done (W) / Time (t) = Energy transferred or converted (E) / Time (t)
Where:

• Power (P) is measured in watts (W).
• Work done (W) is measured in joules (J).
• Energy transferred or converted (E) is measured in joules (J).
• Time (t) is measured in seconds (s).
