Si unit of power: Power is defined as the rate at

Power is defined as the rate at which energy is converted or transferred over time. In the International System of Units (SI), the unit of power is the watt (W), where 1 watt equals 1 joule per second. Power is a scalar quantity, meaning it has magnitude but no direction. It is denoted by P. The image below shows a man lifting a weight, demonstrating his muscular power — a form of physical power generated by the muscles to perform work: Power Formula, Power is defined as the time rate of ... Unit of energy or work done is Joule (J) and time is Second So unit of Power will be joule Sec It is given as : SI unit of power is Watt denoted by W. Was this answer helpful? SI Unit of Power According to popular standards, the SI unit of power is none other than the watt which is represented by the symbol (W). One joule per second is also equal to one watt. Interestingly, the name was kept in recognition of James Watt, who invented the condenser for the steam engine. He also coined the term horsepower, which is the older unit of power. It can be depicted as; Power is work divided by time; hence the SI unit of power is joules/second. Scientists have given a name for this unit, and the unit of power in the SI unit is Watt (named after James Watt, the Scottish inventor of steam engines that helped launch the Industrial revolution.).
