If you're in North America, and you're using a standard PowerPoint (ie. a normal outlet - two vertical bars with a round pin beneath or above), then you've almost certainly got 110 to 125 Volts AC.
If you're in Europe or many places elsewhere - like Australia, for example, then it's possible that you've got 220 to 240 Volts AC.
Using a voltmeter, you can measure the voltage between the pins to determine exactly what voltage is provided.
I'd get an electrician or someone technical to do this for you - the power in the electrical outlet can be DEADLY. Do not attempt this unless you're qualified to do so!
What else can I help you with?
How do you find out the power rating of your power supply?
You can find the power rating of your power supply by looking at the label or sticker on the unit itself. It should indicate the maximum power output in watts (W). You can also check the manufacturer's website or product manual for this information.
You suspect that a power supply is faulty but you use a multimeter to measure its voltage output and find it to be acceptable Why is it still possible that the power supply may be faulty?
Yes, it can be faulty. Some damaged power supplies show good output voltages on the voltage range of a multimeter but, when you connect them, they don't work properly. One possible reason is that maybe an IC in its voltage regulator has a high resistance between the common and the output. You cannot see this by shunting a voltmeter onto it. You have to place a typical load onto the output to test it.
How do you know if you have a 240 power supply or 120 power supply?
Some countries (Europe, Japan) use 120 volt systems. Australia uses 240 volt. One way of find out what voltage is used is to have a look at the pins on the appliances in the same area. 120 volt has round pins on the plug socket. 240 volt systems have 3 flat blades with rounded ends set at 30 degrees to each other around the centre of the socket If you are in the US and have a residential 120/240 volt system and want to know if you should use 120 to ground or 240 volts phase to phase. You should check the voltage rating of the equipment you are wanting to use. Never exceed the voltage rating.
How do you find the voltage?
Voltage can be found using Ohm's Law, which states that voltage (V) is equal to the current (I) flowing through a circuit multiplied by the resistance (R) of the circuit: V = I x R. It can also be measured directly using a voltmeter connected across the components of interest in the circuit.
How many amps in 12 volt dc power supply?
It depends on the power rating of your voltage source. This should be indicated on its nameplate. Divide the power rating (in watts) by the voltage (in volts) to find the rated current available (in amperes).The actual current drawn from the voltage source is, of course, determined by the load, but this value must not exceed the rated current described in the first paragraph.
How do you find power in parallel circuit?
Voltage will be same in all branches. Voltage= Current * Total Resistance
Location of computer power supply in motherboard?
The power supply is usually always located at the top of the computer tower, to the back. Whats easy to find is whatever your power cord from the wall plugs into on the back of your computer, is your power supply box. From there, the power is reduced and sent throughout the computers hardware. (You'll also see that its the box with all the wires are coming out of, inside the computer)
Where Can You Find a 72w Constant Voltage LED Driver AC 90-240V?
This switching power supply is ideal for DIY projects like light bulbs, motors and other electronics. The output voltage is DC 12V constant voltage, which means that no matter what the state of charge on your battery is, this power supply will output the same voltage. This Switching Power Supply is a smart choice for your home or office working environment
How do you find open circuit voltage in circuit?
"Open circuit voltage" is a characteristic of a battery or power supply. You measure it exactly as the term suggests ... disconnect any load from it (or open the ON/OFF switch), and measure the voltage across the terminals of the battery or power supply while it's not supplying current to anything.
How do you find out the power rating of your power supply?
You can find the power rating of your power supply by looking at the label or sticker on the unit itself. It should indicate the maximum power output in watts (W). You can also check the manufacturer's website or product manual for this information.
How do you calculate The Percentage Voltage Drop?
The percentage voltage drop is calculated using the formula: [ \text{Percentage Voltage Drop} = \left( \frac{V_{drop}}{V_{supply}} \right) \times 100 ] where ( V_{drop} ) is the voltage drop across the load or conductor, and ( V_{supply} ) is the supply voltage. Measure the voltage at the load and subtract it from the supply voltage to find ( V_{drop} ). Then, apply the formula to express the voltage drop as a percentage of the supply voltage.
How can I find out what adapters I need for my speakers?
What is important is that the voltage written on your speakers matches the voltage of the power supply. If you check the manufacturers site or return to the store where you purchased them I am sure they can advise you on the right adapter.
How do you find the power factor with true and apparent power?
to put out the power fector you have to divided apparent power with true power.AnswerYou can determine the true power of any load using a wattmeter. To find the apparent power, you use a voltmeter to measure the supply voltage and an ammeter to measure the load current, and multiply the two readings together.If you then want to go on to find the power factor, then you divide the true power by the apparent power. If you want to find the reactive power you use the following equation:(reactive power)2 = (true power)2 x (apparent power)2
How can I find a reliable power outlet adapter for use in the US?
To find a reliable power outlet adapter for use in the US, look for adapters that are certified by reputable organizations like UL or ETL. Check the product specifications to ensure it is compatible with US voltage and plug types. Reading reviews from other customers can also help you determine the reliability of the adapter.
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).
You suspect that a power supply is faulty but you use a multimeter to measure its voltage output and find it to be acceptable Why is it still possible that the power supply may be faulty?

Will a switching power supply work on 277 volts?
Not unless it is rated for that voltage. You can likely find a step down transformer from 277 volt sto 120 volts.
