You can measure the current and power of a 'power supply', using an ammeter and a wattmeter.
With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.

How many vA equal to 1watt?
In a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load. The volt ampere is used to measure the apparent power of a load, and is determined by multiplying the supply voltage by the load current. So the relationship between the watt and the volt ampere depends on the power factor of the load. For example a 100 VA load with a power factor of 0.8 (leading or lagging) will have a true power of 80 W.
Can i replace a 350 watt power supply with 300 watt?
It is not recommended to replace a 350 watt power supply with a 300 watt power supply, as the lower wattage may not provide enough power for your components. It's best to match or exceed the wattage of the original power supply to ensure proper functionality of your system.
What quantity is watt measured in?
A wattmeter is used to measure the power of a load.
What are different measurements of electricity and what aspects of electricity do they measure?
Here are some common units, and what they measure:volt - voltage ampere - current ohm - resistance siemens - conductance hertz - frequency (dimensionless number) - power factor watt - power
Will a 350 watt graphics card work with a 300 watt power supply?
It's not recommended to use a 350 watt graphics card with a 300 watt power supply because the power supply may not be able to provide sufficient power for the graphics card's requirements. This can lead to system instability and potential damage to components. It's best to use a power supply that meets or exceeds the power requirements of the graphics card.
How many kilowats are in 1 amp?
Watts (or kilowatts) and amperes are used to measure different things. Watts is a unit of power; ampere is a unit of current. The relationship (for direct current) is: watt = ampere x volt For AC, the relationship is a bit more complicated: watt = ampere x volt x power factor However, the power factor is often close to one.
What is 5280W to Kilovolt Ampere?
1000v times 5.2amps.AnswerThe watt is used to measure true power. The volt ampere is used to measure apparent power. So, you cannot convert one to the other, as they measure different quantities. However, when the current and voltage are in phase with each other (i.e. having unity power factor), the apparent power will equal the true power.
1mva equal to how many kw?
Basically VA is the same as watt. Kilo means thousand, Mega (abbreviatted M) means a million.AnswerThe watt and the volt ampere are used to measure two different quantities and, so, cannot be directly converted one to the other. The watt is used to measure 'true power', while the volt ampere is used to measure 'apparent power'.There is, though, a relationship between the two, as the true power of a load is equal to its apparent power multiplied by the power factor of that load. So, if you know the power factor (which can vary from 0 to 1), then you can determine the true power of a load, if you are given its apparent power.Incidentally, SI doesn't recognise either the volt ampere (apparent power) or reactive volt ampere (reactive power); all forms of 'power' are measured in watts in SI. The volt ampere and the reactive volt ampere are best described as 'traditional' units.

What power supply should you replace a 175 watt power supply with?
any power supply with at least 175 watts
What is the difference between an amp and a watt?
An amp (ampere) is a unit of electric current, measuring the rate of flow of electricity in a circuit, while a watt is a unit of power, quantifying the rate at which energy is transferred or used. In simple terms, amps measure the amount of electricity flowing, while watts measure the amount of power being consumed or produced.
What is a volt-ampere the product of?
A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.
What quantity is watt measured in?
A wattmeter is used to measure the power of a load.
What is the unit of measure for reactive power?
Volt Amps [volts times amps] is used for reactive and apparent power. Watts (dimensionally the same as volt amps) is used to indicate real power.AnswerReactive power is measured in reactive volt amperes (var).
What are different measurements of electricity and what aspects of electricity do they measure?
Here are some common units, and what they measure:volt - voltage ampere - current ohm - resistance siemens - conductance hertz - frequency (dimensionless number) - power factor watt - power
Why wattmeter measure the reactive power?
A watt meter will measure active power, not reactive power.
