Does the power consumption vary for a device depending if it is connected to 208v or 230v?

no it does not in a way it does it depends on the device and how it is setup. Most today devices need diffrent amount of power for what they are doing if at one moment a device is needing only 12V to operate but the next minute it may need 208V just an example it depends if they device can control the amount of power it consumes however if the device is capaple and wants to use 230V then it will.

How many computers can you connected with a 10 kva UPS?
That will vary a lot, depending on the power consumption of a computer. For example, a laptop computer will use much less power than a desktop computer. You need to add up the power consumption of each of the computers, and check whether this is less than the maximum power output of your UPS.1 kVA sounds like 1 kW (1000 W), but I have read somewhere that due to the deceitful way vendors calculate their numbers, it's actually less by a factor of square root of 2, so around 700 W. However, your UPS may have a sticker that specifies its maximum power output. If it only specifies output voltage (in volts) and maximum output current (in amperes), multiply both together to get watts.

What are three things do electronic hardware devices in order to function?
A method for the CPU to communicate with the device, Software to instruct and control the device, and Electricity to power the device.

How many pcs can be connected to ups?
The limit does not depend on the actual number of PC's that can be connected to a UPS. The limit is based on the total power consumption required by the PCs and the power supply rating of the UPS device. You can add the power consumption of all the PCs based on the number of watts (or amps) listed on a label on the back or side of each PC and compare it to the maximum load specified for the UPS unit.

What is the power consumption on 3 ton air conditioning unit while using a generator?
It would be the same as if it were connected to a utility service. To find the wattage of a device multiply the voltage by the amperage. W = A x V.
How will the UPS work when connected to a normal power supply?
When connected to a normal power supply a UPS takes enough power to keep its battery charged and passes the power through to the device to which it is attached. When normal power fails the UPS uses its batteries to deliver clean power to the attached device.
How long will a 5.4 ah battery last?
It would depend on the power consumption of the device in use.

No set answer to that, it depends on the power consumption of what they're connected to.
Can simple household speakers can be connected in a car?
Its depends on the output power of the device your connecting to.
What is the power rating of a soldering iron which has a current of 2A when connected to a 24V supply?
It depends. The 2A current, did you measure that while the soldering iron was on? Or is it rated at 2A current consumption on the device itself (on the powercable or the stem of the soldering iron). Generaly speaking you can calculted the real power consumption by using P=V*I (thus 2A*24V = 48W). But do remeber that this power consumption is in the steady state, that is, after its switch on and all transient effects have died down. To be safe allow for 3A-4A switching currents that occurs at power on.
Would a multimeter connected in series as part of the circuit measure current or power consumption or voltage or wattage?
Current.
How long do 2 duracell AA batteries last for?
No set answer to that, it depends on the power consumption of whatever they're connected to.
What is the power consumed by a desktop?
The power consumption just depends on your PC configuration. For a decent home user desktop it is 400W for your CPU plus the Power required by your Monitor & Speakers & any other device. The Power consumption increases with increase in hardware inside your cabinet.
