How do you determine Uninterrupted Power Supply size?
The load size in watts is what determines the size of UPS needed. Add up all of the load wattages that you would like to have an uninterrupted power supply. Some UPS units are rated in VA output, for the purposes of this calculation VA is the same as watts. There are many UPS calculators on line if you need any help deciding what to connect to it. Remember the larger the UPS the more the cost is going to be. Read the discuss page for calculator.
Calculate the Power in watts dissipated by a resistor of 1000 ohms with 200 volts across it 2 watts 20 watts 40 watts 400 watts?
Ohms law states that V = I * R I = V/R R = V/I P = I*V Where V = Voltage, I=Current, R = Resistance and P = Power or Watt Watt is the amount of electricity flowing through a line which is (Voltage times Current in (Amperage) = Power or watts) To find the power dissipated by a resistor of 1000 ohms, we first find the current I. The voltage is given as 200volts. Therefore I = V/R = 200/1000 = 0.2Amps We said Power or Watt = I*V Therefore the Power or watts dissipated by a resistor of 1000 ohms will be P=I*V = 200*0.2 = 40 Watts
Does a 100 watts light bulb have 100 watts or does it use 100 watts when lit?
Use 100 watts
Which element is the best for electricity?
Carbon or to be specific diamonds because if you do research you will find out they can withstand about 10,000 watts of electricity
Hp in watts equals?
One hp is 735.5 watts.
How you find ups watts and give detail about VA?
UPS power is not specified in watts.However VA is the equivalent of watts, assuming no phaseshift in the load.
How many watts do a 850 VA ups use?
A 850 VA UPS typically uses around 510 watts when operating at full load. This is because the power factor of most modern UPS systems is around 0.6.
Two measurements are used to rate the capacity of a UPS?
ohms and watts
What two measurements are use to rate the capacity of ups?
VA and Watts
What size of a ups would you need to handle 20 watts?
UPS batteries are typically rated at how many ampere hrs they can supply. IF your 20 Watt device is supplied by 120V then it draws 1/6 amps. (Watts = Amps * Volts for a resistive load). If your UPS were rated for 1 A Hr you could power your device for 6 hours.
How may watt does a load of 3570 watt draw from an UPS of 2010 watt?
If the load wattage is 3570 watts then that is what the load wattage draws. Now by using the expression "draws" maybe you meant to say amps. If it is amperage that you are looking for then the answer can not be given without knowing what the voltage of the system the UPS is tied into.The equation to use is A = Watts/Volts.If a UPS nameplate output rating is 2010 watts then that is the maximum that the UPS is designed for by the manufacturer. Applying a greater load that what the UPS is rated for will void the warranty. Match the load wattage to the UPS's output when calculating what size is needed to operate correctly. This can be done by adding up all of the device wattages that will be connected to it. If the device does not have a wattage shown use the equation above to find the wattage.
What battery back up is recommened to use in sump pump?
My neighbor is running two UPS (Uninterrupted power supplies) computer back-up power supplies. One is 865watts, one is 600 watts. She plugs the sump into a UPS and plugs that UPS into the other UPS. She said one 865 watts isn't enough. They burn-out too fast. The other 600 watts allows it to run 2-3 days (as needed) during a power outage. I don't know how big her sump is. Could make a big difference if its 1/2 or 1/3 hp. I bought 1200 watts in one UPS. It arrives this week. I hope its enough power. I run a 6500 watt Briggs/Stratton generator to power the house and recharge the UPS when the sun rises. 'Cause otherwise, its too loud and wakes the neighbors!
Find amp's when watts and voltage is known?
The formula you are looking for is I = W/E.
What kva generator to run 15Hp motor?
1HP = 746 watts 15 HP = 11190 watts = 11.19 kW You would need a generator of at least 13kW. UPS Distributor for 15 Years.
Two measuremnets to rate capacity of UPS?
1) Rated Protection of the UPS 2) Run Time. Rated protection is usually in KVA or VA (KilliVolt amps for very large UPS or Volt Amps for smaller UPS). This is because UPS typically have multiple outputs like 120V 240V and possibly 12VDC. Some only list WATTS. This assumes the UPS will have only one Voltage output so the Volts X Amps=Watts was already calculated. There is also something called a "Power Factor" that comes in to play. For computers it is ~60% which means if you are backing up a PC it will take more power than you think or the UPS will run for less time than you think because of the power factor. Runtime is usually presented in a chart since it will vary based on the load it is supporting. A battery has a rated Amp/Hour capacity. Amps per hour. You use a fraction of this over time until there is no more energy. Using Ohms Law you can determine the Amps from Watts or KVA/VA. P=IxE or Power ( watts) = Current( amps) x Electrical energy ( Volts) So I (amps) = P(watts) / E ( volts) . There are other factors like the battery charge level, ambient temperature and losses in cabling etc, that affect the run time in amp hours.
Where can you find 55watts on a Chevy prizm?
Watts or Amps? Amps would be the alternator, don't know where you would find watts. Volts X Amps = Watts, for example 12 Volts X 55 Amp Alternator = 660 Watts
How to find watts in physics and what is the formula for calculating it?
To find watts in physics, you can use the formula: Watts Volts x Amps. This formula calculates power, which is measured in watts, by multiplying the voltage (in volts) by the current (in amps) flowing through a circuit.
