"With a volt meter." That last answer could be improved a bit as measured by my dolt meter. One uses a volt meter to measure a 220 outlet by setting it to 'Voltage' or a symbol that looks like a 'V' with a tilde over or beside it for AC. Set the voltage range to 200 or 600 or something close. Put one lead in a socket on the volt meter that probably says 'COM', and put the other in the 'V' socket on the meter. You should read zeroes whether the leads are touching or not. There will be (probably) 3 or 4 outlet socket holes. If 3, two will look slanted and the third will either be straight or have an 'L' shape to it. The L or straight socket is your ground/common socket. The two slanted sockets are your hot sockets. Putting a lead in each of the slanted sockets (being careful to hold the leads by the non-metalic part) should yield your reading, about 220-240.

What is the period of the voltage waveform out of a wall outlet?
60 seconds
How much voltage does a wall outlet supply?
Usually 110 volts
How much voltage does a wall outlet usually supply?
Usually 110 volts
Will a 12 volt light plug into a standard wall outlet?
No, it will cause the bulb to blow. A 12 volt light is DC voltage and your home outlet is AC voltage.
If you measure the current coming from a wall outlet in your house will it give the same reading the meter uses to compute your home energy use?
No. Current does not come from a wall outlet unless the wall outlet is part of a complete circuit.
What is AC voltage at wall outlet?
I think it depends on country to country. In India, it is 220V-230V
Should an all-in-one scanner be plugged into the wall outlet?
Yes, an all-in-one scanner should be plugged into a wall outlet to ensure proper power supply and functionality. It is recommended to follow the manufacturer's instructions and use the provided power adapter to connect the scanner to a power source.
Could low voltage from a wall outlet cause a home theater system DVD amlifier to not turn on?

How do you find out the power supply voltage from my wall outlet?
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!
I have 230 wall ac unit I want to replace can you buy a 115 voltage unit and use it?
As long as the outlet is right for the 115, you can buy it.
What do you use to check for a line voltage sags?
There is a type of voltmeter which prints out a graph of voltage against time. This can be left installed in a wall outlet for a period of time, such as a week, and it will provide a record of the supply voltage variation over that period.
The wiring in the wall of your house to and from an outlet has a total resistance of typically 0.12 ohms suppose a device plugged into a 120 V outlet draws 10 A of current What is the voltage drop?
The voltage drop across the wiring in the wall is calculated using Ohm's Law: V = I * R, where V is the voltage drop, I is the current, and R is the resistance. Plugging in the values, V = 10 A * 0.12 ohms = 1.2 V. Therefore, the voltage drop across the wiring in the wall is 1.2 V.
