What is a watt?
Watts measure power--kilowatt-hours measure energy. When you get your utility bill, the electricity you've used is measured in kilowatt -hours (kWh). While a watt is a measure of power, a kWh is a measure of energy. Energy is defined as the capacity to do work, such as creating heat, light, or motion. If you run a 60-watt lightbulb ...
What is watts in electrical?
Power is a measure of the rate at which energy flows, and in electrical systems it is measured in watts (W). Watts are basically the miles-per-hour measurement of the electrical world--they tell you how fast the electrons are speeding down the highway.
How much power does a 60 watt lightbulb use?
A 60-watt lightbulb will consume electricity at a rate of 60 watts. A laborer working through the day will put out 75 watts of power. A medium-sized car might consume 100,000 watts. (One horsepower is equivalent to 750 watts, so that's a 286-hp car.)

What is watt power?
A watt (W) is a unit of power, and power is the rate at which energy is produced or consumed. Think of watts as a measure of electrical flow. Does an electrical device need a big flow or a small flow to work? For example, a 100 W light bulb uses energy at a higher rate than a 60 W bulb; this means that the 100 W light bulb needs a bigger “flow” to work. Likewise, the rate at which your solar energy system “flows” power into your home is measured in watts.
What is the analogy of Watts and Watt Hours?
A common analogy for watts and watt-hours is speed and distance. Speed is a rate of how fast you drive at an instant in time; distance is the length, or amount that you drive over a period of time. For example, if you drive at a constant rate of 60 miles per hour for one hour, then you will have traveled 60 miles.
