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 t...
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 ...
Where P is the 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 ...
How to convert DC current to AC current with a formula How to convert calories to joules with a formula A DC motor consumes 36 MJ of energy when connected to 230 V FOR 2.5 hours. a. Calculate how many kWh is the amount of energy mentioned above. b. The power taken by the motor fro...
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...
How long will a battery last calculator,AH to Watts and watt-hours, battery capacity, how to calculate battery life, run-time calculation Resources for designing equipment using battery packs from PowerStream
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 is the power consumption when consuming 6kWh for 3 hours? Solution: P(kW)= 6kWh / 3h = 2kW kW to mW, W, MW, GW, dBm, dBW conversion calculator Convert kilowatt to milliwatt, watt, megawatt, gigawatt, dBm, dBW. Enter the power in one of the text boxes and press theConvert...
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 ...
Readings are taken during each billing period. The common billing unit is kilowatt-hour (kWh), which equals the use of one kilowatt of power for one hour or 3,600,000 joules. The Watt-Hour Meter is often referred to as an energy meter or electric meter or electricity meter, or electrica...
