How Much Power Is Consumed By A Load Drawing 5 A With 120...

If the power rating of the refrigerator is 700 W, how much electrical energy does the refrigerator use in 1 33. Calculate the resistance of a wire if 0.5 V across it causes a current of 2.5 A to flow. 35. An iron draws 6.0 A of current when operating in a country with a mains supply of 120 V. Calculate the...The power consumption of a laptop can be tricky to estimate. This is because amount of power a computer uses when it's on is not constant. To get an even more accurate estimate of power usage, there are apps available for download that will show you how much power your computer is using at...I can see it requires an expert to answer this problem. Textbooks only go so far, but reality goes further. 120V * 5 Amps = 600VA. Our variable will always be the current draw. So if you use a UPS, make sure that what ever you plug into it, add up all your amp values then mulitiply your voltage and then...mps with 120v AC across it? The cards are meant to be seen as a digital flashcard as they appear double sided, or rather hide the answer giving you the opportunity to think about the question at hand and answer it in your head or on a sheet before revealing the correct answer to yourself or studying...How much power does the heater consume? Assuming your current and voltage are RMS values, and that the heater is a purely resistive load, the heater will consume 15 x 120 = 1800W or 1.8 kW of real power whenever it is turned How long it is operated doesn't change its power consumption.

How To Calculate Watts Per Hour For Each Electronic Device

Sorry it is long, but I figured to explain a little more instead of just saying no. Do PSU use the rating as power? If your system needs more, you might come across issues like throttling hardware or out right hard shutdowns. The efficiency standards let you know how much extra power is used or...As the load reduces it will draw less current,that is obvious. And for our use voltage remains constant and power factor as well as efficiency is also previously But the starting requires more power.... Can I know how much percentage of rated power is required at start up and for continuous running ?This energy is consumed by force of friction that acts opposite to the direction of motion. They normally return more than 90% of the electric power delivered to them in useful power. It generally cannot give back all of it. Make sure that you write the formulas with horizontal fraction bars.The text below, about electrical power, is from a home improvements magazine The amount of current, in amps, required by an electrical appliance- such To calculate the required current, simply take the wattage and divide it by the voltage of the electrical supply in your home- around 230 volts in most of...

How much power is consumed by a load drawing 5 A with 120...

Or power consumption remains constant/same in both cases? What I think is that, Power drawn by motor should increase as we increase the load on motor. Put a large motor like a vacuum cleaner or a circular saw on a long enstension lead with an incandescent lamp. at night start the motor up and...1. How much power is consumed by a load drawing 5 A with 120 V across it? 600 VA. 2. You suspect that a power supply is faulty, but you use a multimeter to measure Because power problems can be intermittent. 3. Someone asks you for help with a computer that hangs out at odd times.A load will always draw its rated power. If you have increased your voltage to twice then the current drawn by the device will become half but the power consumed will It will decrease the effective load resistance across the power supply terminals, increase the total current through the load, and...How much power is consumed by a load drawing 5 A with 120 V across it? What is a reasonable wattage capacity for a power supply to be used with a system that contains a DVD drive, three hard drives, and a high-end video card?The power consumed by a load (resistance) is given by. For this load, we have: V = 120 V. I = 5 A. Substituting

I will see it requires a professional to reply to this drawback. Textbooks handiest pass to this point, however reality goes additional.

120V * 5 Amps = 600VA. (No question about it)

No one even thought about power issue. That my buddy is.778 multiplier, because you most effective use about .778 of the 60 Hertz sine wave on the out put.

600 * .778 = 466.80 watts.

And after all this equation is designed for switch mode power provides.

This is a good instance. Say you'll purchase a UPS on your laptop. Your power supply is 450 watts. Is that 600VA UPS, large enough for this system, or would you've got problems? Answer, you can have issues. You would say, why? you could have 466.8 watts to play with. To extend on this answer, it is very simple. The 466.Eight watts is the entire load out put when the unit is sizzling. When the unit is cold, or the transformer windings from the inverter are cold and now not on but, you may have induction from the inverter that can bite up 50 watts on a start up. So the equation is now not completed but. You need to subtract 50 watts on the get started up of your by-pass of your inverter so the actual worth is 416 watts on a complete load, and you will not get 15 minutes for a run time. Fact is, your inverter will ultimately crash and burn with a quick life for those who continuously drain your battery. Here is something we will upload to the equation.

(*5*) power provides draw 1/Three more power, like telephone systems power supplies.

So we have to add 1/Three more to the load that is 600Watts. We need extra power. There is completely indisputably in my thoughts that this 600VA UPS will crash and burn in much less the 6 weeks or months. APC six weeks, Powerware six months.

I would use a 750-watt to 800 watt UPS with a switch mode power provide. On a phone gadget linear power supply I might use a 1000VA UPS.

One final thing. Our constant will at all times be 120V. Our variable will all the time be the current draw. So in case you use a UPS, be sure that what ever you plug into it, upload up all your amp values then mulitiply your voltage after which you are going to have a VA worth. Don't put out of your mind the power factor. It will idiot you, to not point out if you plug in a wally wart transformer in your you UPS. That ends these days's lesson on UPS and Power.

I do take guidelines, or possibly an apple or two!
