Different batteries have different capacities, and will therefore store a different amount of energy - and require a different power if you want to charge them in the same time.

How many watts if 4 kW for 6 hours?
"Watt" is a rate of using energy."4 kW" means 4,000 watts."4 kW for 6 hours" means 4,000 watts for 6 hours.If you use energy at the rate of 4 kW for 6 hours, then altogether you use24 kilowatt-hours, or 24,000 watt-hours, or 86,400,000 joules.
What is the consumption of units for 60W bulb for 6 hours?
Convert the watts to kilowatts (divide watts by 1000), and multiply the result by the number of hours. Answer is in kWh, the unit used by the electrical companies for billing.
If i use 7000 watts per day how many amp hours per day would this be?
To obtain amps from watts a voltage must be given.
What does 1000 watt-hours equal?
Your basal metabolic rate approximates 100 watts. Thus 1000 watt-hours equals about 10 hours of your existence.
How many watts per hour to equal 1000 btu's?
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

How many watts to charge a 12v battery direct in 6 hours?
Different batteries have different capacities, and will therefore store a different amount of energy - and require a different power if you want to charge them in the same time.
Formula to figure out watts when you have voltage and mAh?
Voltage times current is equivalent to power (watts). You need to keep in mind that milli amp hours (mAh) is amps with a unit of time - it's a specific amount of current for 1 hour. Watts is an instananeous measurement; watt hours is the equivalent you should be looking for. there is no direct conversion for watts from voltage and mAh.
How do you convert amps to amp hours?
volts times amps equals watts, a measure of power. Amps times hours equals amp-hours, a measure of electric charge. Electric charge times voltage is energy. So 120 volts at 10 amps for 4 hours would pass 40 amp-hours of charge, the power would be 1200 watts and the energy would be 4800 watt-hours or 4.8 kilowatt-hours. So volts times amp-hours equals energy in watt-hours.
Is Naomi Watts in a direct tv ad?
Yes, that is Naomi Watts. http://www.movienewz.com/king-kong-direct-tv-commercial/
How many watts are in 30 volts?
There is no direct relationship between watts and volts. Watts = volts x current in amps.
What is the difference between using 100 watts for 2 hours or 50 watts for 4 hours?
In theory, no difference.
How much does it cost to use 5 watts 24 hours 31 days a month?
3.72kwh * per unit charge,e.g if per unit charge is Rs 7 then the cost 3.72*7=26.04.
Can you charge a battery with solar panel producing 245 watts?
You can't charge the battery with those 245 watts unless they are being 'pumped into' the battery at a higher voltage than the battery puts out. If you can exceed the voltage of the battery, that 245 watts will definitely charge a battery.
77000 watts for 30 days is how many kilowatt hours?
Convert the watts to kilowatts, and the days to hours. Then multiply kilowatts x hours to get kWh.
Find the kilowatt hours used if 300 watts are used for 8 hours?
300 watts 0.3 kilowatts; 0.3kilowatts X 8 hours 2.4 kilowatt-hours
How many watt-hours are in 6 kilowatt-hours?
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
How do you convert watts to wattshour?
You multiply the number of watts by the number of hours those watts are used, resulting in watt-hours. Electrical usage is often billed in increments of kilo-watt-hours, or how many thousands of watt-hours were used during the billing period.
