Web20 apr. 2011 · If you run a 60-watt lightbulb for one hour, you've used 60 watt-hours, or 0.06 kilowatt-hours, since a kWh is 1,000 watt-hours. In other words, 0.06 kWh is the amount of energy you need to run a lightbulb for an hour. Homes are typically charged only for the electricity they use, measured in kWh. WebSimple Ohms Law Formula Amps (i)= watts/ volts so 1000 watts / 120 volts = 8.3 amps of draw to produce that power output. Now that you have the electrical information you can convert the light bulb watts to amps, that is the higher measure of … Web1 Wh = 1 Watt * 1 hour = 1 J/s * 3600 s = 3600 J. That's the energy stored in the battery, which is completely not related to time. The larger the number, the more energy it supplies. 1Wh means if a device's power is 1W, it can last for 1 hour with that energy. However usage time depends on the power consumption, not energy. can foam be used on electrical fires
