How do you find the power factor for a 240 V and 480 V single phase heaters?
Power factor is the cosine of the phase angle -i.e. the angle by which the load current lags or leads the supply voltage. Heaters are resistive loads (although not 'purely' resistive), which means that the load current is practically in phase with the supply voltage, making the resulting power very close to unity (1).
Can you use 36V 16.6 A power supply to 38V 15 A load?
Maybe. The power supply has a nominal rating of 36V and the load as a nominal requirement of 38V, but both values have tolerances.The power supply may in reality support 36V +/- 5%, and the load may accept a supply voltage in the 32..42V range, for example. However, tolerances and real minimum requirements may also work the other way.To find out whether this combination works, you should study the respective technical data sheets. It is also fairly safe to simply try: since the power supply's nominal voltage is less than the load's nominal input voltage, you're unlikely to cause any harm by trying. At your own risk of course.Note that a simple experiment may not be conclusive. The load may be working fine under idle or light use conditions, but when it draws more energy, the power supply may collapse.
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
How do you find out total power of two lamps connected in series?
The rated powers, printed on each lamp, will no longer apply. You will need to measure the load current (I) drawn by the two lamps, together with the supply voltage (U), and multiply the two values together: Power = U I
How long will a 1000VA inverter provides backup power with 100 Amps Battery for 3 fans 3 lights and 1 tv?
The running time depends on two things: the actual power the inverter can supply, and the actual power drain of the loads. A 1000 VA inverter may be able to supply 1000 VA, but it battery size determines *how long* it can supply power for. A 100 amp battery can probably supply 10 amps for 10 hours (100 amp-hours), but it may only supply 100 amps for perhaps 45 minutes - if it does not overheat! Generally, batteries give less effective power at higher power drain. You also need to know how efficient your inverter is - it may be 90%-plus, it may be as bad as 75% or less. So you will need to (1) find out how much power your appliances draw (let's say its 300 watts), then (2) examine the specifications for the inverter-battery combination to discover how long they can support your power drain. Be aware that 300 watts load is over 25 amps current drain at 12 volts, so you are already getting away from the 100 amp rating, to a lower value due to the high power drain on the battery.
Where can one find projector ceiling mounts?
One can find projector ceiling mounts online at Projector Mount Store, BH Photo Video, eBay, and Amazon. They can also be found at office supply stores like Office Depot and Staples.
Sanyo pro xtrax multiverse projector The image projected on the board is faded and almost un readable is this the lamp failing?
The most probable cause of a faded image is a failing bulb but this is not always the case. You might find when you replace the bulb it make little difference, if this happens it is a sign the the power supply in the projector is failing.
How do you find a model make of projector with chasis number of sanyo company?
You will find it molded into the casing or on a metal plate close to the power cord input.
Where can I find a power cord for an old Cine projector?
Don't know if their website is still up but you might try parts.com.
Where can one find more information about projector screens for sale?
You can find more information about projector screens for sale at the shops that sell them. Projector Pros, Staples, Best Buy, and Amazon all have information about projector screens.
You have spark to your spark plug but you don't seem to have power to injectors 6 and 7 How do you find the power supply for them?
To find the power supply look at a schematic for the fuel injection system in a service manual for the vehicle they are in.
Where can I purchase a slide projector?
Projectors for presentations can easily be found at most office supply stores, like OfficeMax, Office Depot or Staples. You could also find them at computer stores like MicroCenter. If you don't need one immediately and can wait for shipping, you might find a good deal on a projector at Amazon.com.
What should you do with a power supply if it is too hot to touch?
Find out what the VA capacity of the power supply is and then add up the connected load in VA (volts x amps). If the load totals are greater that the VA power supply capacity then this is where the heat is coming from. The power supply is overloaded. Remove some of the load or get a bigger capacity power supply.
