Watts are like miles-per-hour
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.
Are watts calculated per hour?
A Watt Hour is a unit of measurement for power over a period of time (an hour), or in our case, a way of measuring capacity. One Watt hour is equal to one Watt of average power flow over an hour. One Watt over four hours would be four Watt Hours of power.
How many watts are used in an hour?
One kilowatt-hour is equal to 1,000 watts for one hour. For instance, a 40-watt light bulb uses 40 watts of energy every hour.
