Explanation
In physics, power is the rate at which work is done or the amount of energy transferred or converted per second. It is thermodynamic concept. Electrical power is a similar concept within the electrical components where power is carried. Electric power is measured in watts (W) after James Watt, the Scottish engineer. Watt is a unit of power defined as one joule per second. On the other hand, volt is a unit of the electromotive force, the volt measures how much "effort" a power source (such as a battery or generator) is exerting over charge carriers (like electrons). In brief, watt is the rate of energy transfer used by a circuit component whereas volt is the electrical potential difference known as voltage. While both watts and volts apply to electrical circuits, they do not mean the same thing.
