"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.
No reason not to as long as the wall outlet is the correct voltage. most are designed to be plugged into a 110v outlet.
60 seconds
Usually 110 volts

No, it will cause the bulb to blow. A 12 volt light is DC voltage and your home outlet is AC voltage.
No. Current does not come from a wall outlet unless the wall outlet is part of a complete circuit.
I think it depends on country to country. In India, it is 220V-230V

As long as the outlet is right for the 115, you can buy it.
A dedicated wall outlet is the only one on the circuit.
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.
Assume the supply as DC (Only resistance given) Voltage drop = 10X10X0.12 = 12V (approx)
