When replacing a power supply what is more important the the ampere or the volt ampere for the power output?
The question is moot, here's why: First of all, the replacement must supply the correct voltage. This cannot change. You always replace a 12V supply with a 12V supply. If the replacement supply has the correct amperage, it will also have the correct volt-amperes, since (by our definition) the voltage is the same. Say the old supply was 12V, 2A. This is a 24VA supply (12 X 2 = 24). The new supply also must be 12V, so which is more important, amperes, or VA? As you can see, if we make sure the new supply is 2A, it will also mean it supplies 24VA (12 X 2 = 24). If we make sure the new supply is 24 VA it will obviously supply 2A (24/12 = 2). So, assuming the voltage stays the same, matching either VA or amperes automatically means the other value is correct.

What is impact ampere in 50Hz motor connected to 60Hz?
What effect will be there on the motor (Induction) output power when a 100kW 50hz motor is connected to a 60hz power supply.
How long will a battery 12 ampere-hour rating supply 144 watt load?
An ampere-hour rating is a relatavistic indication of how long a battery can supply a specific current.It is not possible to determine the run time when you only gave watts, but watts are volts times amps, and you did not supply the volts.
What is mean by 600va?
VA stands for Volt-ampere. 1 VA is equal to 1 Watt. So 600va is about 600 watts. This can be confusing because a power supply rated at 600va will not put out 600 watts due to reactance. The power supply contains an inductor or capacitor so the actual output will be around 1/2 to 2/3 of the VA.
When switch is off of power supply output shown on the multimeter is negative voltage from power supply?
Yes.
Would a relay be wired differently for a sourcing and sinking output module?
Yes. For sourcing output, the relay coil is wired to (common or ground) and the output terminal. For sinking output, the relay is wired to (voltage supply or hot) and the output terminal.

What is competitive supply?
There is competitive supply,if an increase in the output of one commodity requires a reduction in the output of another commodity.

Output DC power supply?
????????????????
Power supply units are rated in?
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
Will government tax per unit of output reduces supply?
Yes; a government tax per unit of output reduces supply.
How is a market supply curve similar to an individual supply curve?
The individual supply curve is the supply curve of a single firm producing output. Now say there are X individual producers there at any price P* the total available output is the output of all X producers ( a horizontal summation) this total of each individual supply curve gives the market supply curve. Put it simply all firms sell their output in the market.
How calculate kilovolt-ampere?
25kv=?kwAnswerA volt ampere (V.A) is the unit of apparent power, and applies to AC circuits that contain resistance and reactance. Apparent power is the vector sum of true power and reactive power. A kilovolt ampere is 1000 V.A. The volt ampere is the product of supply voltage and load current.
What is a triple output supply?
Triple output power supply have 3 channels,2 of these channels have variable output voltage up to 25-30 volts and current of the this channel can also be varied and the third channel if fixed and have 5 volts output.
Is power supply input or output devices?
Output - because it is outputting power to the rest of the device
Why power supply an output device?
because it is devices
