If a device doesn't give its power rating in kVA (or VA), then it can be calculated pretty easily: (volt-amperes) VA = V (voltage) x A (maximum amperage) (kilovolt-amperes) kVA = VA (volt-amperes) / 1000
The difference between desktop computer and personal computer is that desktop computer is for everyone and personal computer is for your own self!
The best desktop computer to have is a silver sony
With a sponge
an example is PC.
The Apollo Guidance Computer, which took us to the moon was an embedded computer long before any desktop computer existed. There were missile guidance computers before that (e.g. Bomark & Minuteman I) that were embedded.

Depends on the kva rating of the devices to be tested using a transformer.
To calculate the kVA rating of the transformer, you can use the formula: kVA = (Voltage × Current) / 1000. In this case, the secondary winding delivers 10 amps at 480 volts. Therefore, the kVA rating is (480 V × 10 A) / 1000 = 4.8 kVA.
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
VA or KVA or MVA
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
You can tap off approximately 833 200 amp panels from a 250 kVA transformer. This calculation is based on dividing the kVA rating of the transformer by the current rating of the panel.
Sir, The rating of ac generator is always calculated in KVA.So rating of generator as asked in your question is 360 KVA Sir, The rating of ac generator is always calculated in KVA.So rating of generator as asked in your question is 360 KVA
The number of computers a 10 kVA UPS can support depends on the power consumption of each computer. On average, a standard desktop computer with monitor uses about 300–400 watts.The number of computers a 10 kVA UPS can support depends on the power consumption of each computer. On average, a standard desktop computer with monitor uses about 300–400 watts. To estimate: 10 kVA UPS ≈ 8000 watts (assuming 0.8 power factor) If each computer uses 400 watts: 8000 ÷ 400 = 20 computers So, a 10 kVA UPS can support around 18 to 20 standard computers for a limited time, depending on the load, battery condition, and runtime required.
as while designing alternator we have to consider two ckt. i.e. electrical ckt.& magnetic ckt. and electrical ckt.is designing by considering current & magnetic by volt.thats why rating is in kva.
The kV.A (not 'kva') rating is the total apparent power of the machine. So a 75 kV.A machine is 25 kV.A per phase.
