Watts means the electric power and kilowatthours means electric energy. Compare: http://en.wikipedia.org/wiki/Electric_power http://en.wikipedia.org/wiki/Power http://en.wikipedia.org/wiki/Electric_energy http://en.wikipedia.org/wiki/Energy Cheers ebs
Kilowatthours was created in 1998.
Watts = Volts / Ohms Watts = Volts x Amps
Kilo = 1000. Watts the produce of Amps x Volts. One hour is not divided up into kilowatt hours, it is the use of 1000 watts over a period of one hour.
Electrical power is measured in Watts, or multiples of Watts, like kilowatts or megawatts. Electrical energy is power x time, usually kilowatthours or megawatthours.(kWh or MWh)
That is impossible. That are different things.
The main difference between VA and watts in measuring electrical power is that VA (volt-amps) represents the apparent power in an electrical circuit, which includes both real power (watts) and reactive power. Watts, on the other hand, only measure the real power consumed by a device. In simple terms, VA accounts for the total power used by a device, while watts measure the actual usable power.
The 100W light bulb is brighter than the 60W light bulb. The difference in brightness is 40 watts.
746 watts = 1 HP.
Converting AC to watts and DC to watts involves the same formula: watts = volts x amps. However, for AC circuits, an additional factor called power factor (cosine of the phase angle difference between voltage and current) needs to be considered to account for any phase difference between voltage and current.
No, each manufacturer has their own method, use the specs. for a ballpark figure. You can't hear the difference between 100 watts and 120 watts.
Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
1 mega watt is equal to 1 million watt or 1000000 watt.
