Does anybody know how much power does it take to run 20 Watts for 96hrs?
Answer:
power is constant at 20 watts but if you need the cost then it will be multiply by 96 hours, equals 1,920 watthours or 1.92 kwhr.(power consumption)
I have no idea, but you have me curious now.
1.92 kilowatt hours. One kilowatt hour costs about .14 cents in major cities. So you will spend about 27 cents total.
20 watts multiplied by 96 hours. If there is any kind of conversion of power, such as DC to AC then you need to figure in at least 10% more watts for that conversion. Personally, I'd use 15%.
The power used will be 20 x 96 watt-hours, i.e. 1920 watt-hours, or 1.92kWh.
You may have to revise your question because electrical power is Watt. Therefore the answer would be 96 x 20 Watt/hr.
Power is P=I(amp) x E(volts)
20= I(amps) x12vdc
I(amp) = 20watts/12vdc= 1.66...amps
so to maintain 20 watts for 96 hours
you need a battery that will produce 1.66 amps /hour for 96 hours or a battery with a 159/160 amps reserve...
Now Power is described as work acting through time so amps is not the power but the pressure to push a flow(Volts) to create work which is your wattage number...just thought i might clear that up.Have a good one from the E!!
The no. of wattage consumed would be:
20 w * 96 / 1,000 = 1.96 kilowatt hours
It's not quite expensive at all in terms of electric bill.
Your question is totally incoherent. Power is measured in Watts. To provide enough power for something that consumes 20 Watts, for any period of time, you need a 20 Watt power source.
20W*96* = 1920Whrs.
chk how much ur local eletrical company charges u per Whr por KWhr and then calculate.
20 Watts is the power. It is the voltage times the current. 20 watts over 96 hours is a unit of energy, not power.
It sounds like you are trying to get a battery to provide you enough energy to provide 20 Watts for 96 hours. The battery will have a voltage and and amp hours rating. If , for example, it is a 12V battery, you will draw 1.67 amps to provide 20 Watts. To do this for 96 hours you need a battery with a capacity of at least 96 times 1.67 amp hours.
you need to know the voltage first.
