I have never seen a 100 Volt rated outlet. Usually outlets would be rated for 110 to 120 volts for residential use, or maybe 150 volts. The rating is separate from what voltage the outlet is providing. If your outlet is supplying 100 volts, as measured by an accurate voltmeter, you have some problem in your wiring or a faulty outlet. If there is only 100 volts at the outlet get an electrician to diagnose the problem if you are not completely familiar with home wiring.
In general you should never use an outlet that has a voltage or current rating less that the device will consume.
If it does not come with a plug on it, no. If it is made for direct wire, then 99.9% chance is that it is a 240 volt unit. If you plug it into a 120 volt outlet your water will barely get warm.
No. First off, the plug will be different. And even if you replace the plug, it won't work right on the wrong voltage
No, it is not recommended to plug a 125 volt 30 amp plug into a 120 volt 30 amp outlet. The voltage difference may cause damage to the equipment and pose a safety hazard. It is important to use the correct voltage outlets for your devices.
No, the plugs are different to prevent this and even if you could the lamp would be very dim.
Yes, you can plug a 220 volt, 1500 watt, 60 Hz cooker into a regular 220 volt outlet, provided that the outlet is rated for the same voltage and can handle the power requirements of the cooker. Ensure the outlet is in good condition and properly grounded. Always check the circuit's amperage rating to avoid overloading it. If you're unsure, consult an electrician for safety.
Yes.

Yes.
The bulb will be about half as bright.
Yes
A device that operates on a 220 volt 20 amp plug requires a special type of electrical outlet called a NEMA 6-20 outlet.
A device that operates on a 240 volt 50 amp plug requires a NEMA 6-50 electrical outlet.

If it does not come with a plug on it, no. If it is made for direct wire, then 99.9% chance is that it is a 240 volt unit. If you plug it into a 120 volt outlet your water will barely get warm.
No, it will cause the bulb to blow. A 12 volt light is DC voltage and your home outlet is AC voltage.
Take the plug in your hand, and insert the plug into the wall outlet.
