How to convert electric power in watts (W) to energy in joules (J).You can calculate joules from watts and seconds, but you can't convert watts to joules since watt and joule units represent different quantities.Watts to joules calculation formulaThe energy E in joules (J) is equal to ...
How to convertelectric powerinwatts (W)to energy in kilojoules (kJ). You can calculate kilojoules from watts and seconds, but you can't convert watts to kilojoules since watt and kilojoule units represent different quantities. Watts to kJ calculation formula The energyEin kilojoules (kJ) is eq...
Watt-hours per square meter and lux-hours are two ways of describing the energy that light transmits. The first, watt-hours, considers the light source's total power output. Lux-hours, however, describes perceived luminous intensity, in terms of how much light the human eye observes. Many ...
How to convert watts to kilowatts with a formula What is the formula to convert watts to amps? How to convert DC power to AC power with a formula Convert joules to kilowatt hours How many kW is required to lift a weight of 600 kg by 1 m in 1 sec? A 200 kVA, U1N/U2N = 10/6....
power in watts (or joules per second), V is the potential difference in volts, and I is the current in amperes. Power can also be expressed in volt-amperes and horsepower (HP), with the latter often used in everyday engines such as those in motor vehicles. 1 HP is equal to 746 ...
Similarly, to convert volts-amps (VA) to watts in an AC circuit, you would use:watts = VA x power factor. The power factor in resistive circuits is 1, meaning that all of the energy being used is effectively utilized. However, inductive or capacitive components can cause a phase differenc...

If you'd like to learn more about calorific values you can find informationhere. Step 6 The final step is to take thermal energy measured in Mega joules per cubic metre (MJ/m3) and convert it into kilowatts per hour. 1 Watt is a derived unit of power defined as 1 Joule per second....
What unit is represented by (a) joule per coulomb (b) coulomb per second (c) watt second? How much time does it take a pulse of light to travel through 140 m of water? The heart of a resting adult pumps blood at a rate of 5.00 L/min. (a) Convert this ...
surges. Before you buy, make sure the surge protector has aclamping voltage(how much electricity will trigger it) of at least 330, anenergy dissipationrating (how much electricity will cause it to fail) of at least 400 joules, and aresponse timeof 10 nanoseconds or less [source: Alliant ...
