Work is expressed in newton-meters, or the simplification, joules (J). The rate which work is done is called power. Power equals work divided by time. If work is in joules (J) and time is in seconds (s), power is expressed in joules/second, or the simplification watt (W). James Watt was a British scientist who invented the steam engine.

The relation between kilowatt-hours and joules is easy to determine: 1 kWh = 1,000 J/s x 3,600 s = 3.6 x 106 J. Again, we see how small a joule is in practical terms. One kWh is the energy required to power ten 100-watt lightbulbs for one hour. The average home in the U.S. uses about 10,000 kWh of …

Use conversion factors to show how many joules of energy you get when you buy 1 kilowatt-hour of electricity. Answer: Using conversion factors, it can be shown that 1 kilo-watt*hour is equivalent to 3.6 x 106 Joules. First, convert 1 kW-hr to 1000 Watt-hours. Then convert 1000 Watt-hours to 3.6 x 106 Watt …

Conversion from watt-hours to Joules: 1 watt-hour (Wh) = 3.6 * 10^3 Joules, For 960Wh : (3.6 * 10^3 Joules/Wh) * (960Wh) = 3,456,000 Joules of energy With 12 batteries, for the current motor controllor we're using, that means 1440 watt-hours for the entire battery array.

An old fashioned light bulb may convert electrical power into light and heat at a rate of 100 Watts (remember , that’s a rate of 100 Joules every sec). Your body converts about 2000 Calories of food energy into movement and heat every day—that’s about 50 W—just to keep yourself warm.
