The concept of electrical power was developed through the pioneering work of scientists like James Watt, Georg Ohm, and James Prescott Joule in the 18th and 19th centuries. Watt, though primarily known for steam engine innovations, gave us the unit of power we use today. Ohm established the relationship between voltage and current, while Joule demonstrated how electrical energy converts to heat.

In practical terms, electrical power represents the rate at which energy is transferred in an electrical circuit. It's a measure of how quickly electrical energy is being used or delivered, affecting everything from your monthly electric bill to the design requirements of every electronic device you use.
