It will power two 400 watt lamps.
The amount of wind power needed to light a bulb depends on the size of the bulb, its wattage, and the efficiency of the wind turbine. As a rough estimate, a 60-watt bulb could be powered by a small wind turbine with an output of around 400-1000 watts.
Normally speaking, a 3500 watt generator can typically power appliances such as refrigerator (500-800 watts), laptop (50-100 watts), television (100-400 watts), stereo system (200-400 watts), air conditioner (1,000-2,000 watts), electric stove (1,000-2,500 watts), lights (50-100 watts). It's important to check the specific power requirements of your appliances as they can vary.
If the TV and refrigerator together use (are rated at) less that 340 watts, then the generator will power them until it runs out of gas. It would have to be a very small, efficient refrigerator as they're usually high current devices. The TV would also have to be small and efficient, but that would be easier to find.
One 400 watt bulb is equivalent to four 100 watt bulbs in terms of total power output.
1 Joule is 1 Watt-Second. 1 Watt Hour is 3600 Watt-Second or 3600 Joules. 400 Watt-Hours is 1440000 Joules.
800 watt should be fine
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
It depends on the power requirements of the sump pump. A 2400 watt generator should be able to run a typical sump pump that requires around 800-1200 watts, but you should check the specific power requirements of your pump to be sure.
To calculate a cost in kW/h a time interval has to be stated. How long is the 400 watt heater going to be on in a 24 hour period. You also have to state what you are being charged from the utility power company per kW/h.
Yes, you can plug in a 12 volt pump to a 400 watt inverter as long as the pump's power requirements do not exceed 400 watts. Make sure the inverter is designed to convert 12 volts DC to 120 volts AC to power the pump effectively.
About one watt of heat. A 1500 watt heater will warm a 400 square foot room in the winter months. one watt is a very small volume of heat.AnswerHeat is measured in joules. A watt is equivalent to a joule per second. So your answer is that a watt produces one joule of heat every second.
