120 volt used on a 240 volts system
The 120 volt kettle run off of 240 volt will have a wattage output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
For example if an ordinary 1000 watt kettle's supply is 120 volts, the current of the kettle will be, I = W/E 1000/120 = 8.3 amps.
The resistance of the kettle is R = W/I (squared) =1000/8.3 x 8.3 (69) = 14.5 ohms.
Applying 240 volts on the same kettle whose resistance is 14.5 ohms results in a new kettle wattage rating. W = E (squared)/R = 240 x 240 (57600)/14.5 = 3972 watts.
This is 2972 watts, almost 300%, higher than the manufacturer's designed safety rating.
W = watts, I = amperage, R = resistance in ohms and E = voltage.

How can you plug my 220 dryer inTo the existing 110 Plug?
To safely connect a 220-volt dryer to a 110-volt outlet, you cannot directly plug it in, as the voltage and amperage requirements are different. Instead, you should consult a licensed electrician to either install a dedicated 220-volt outlet or use a transformer that can convert the voltage appropriately. Attempting to use a 220-volt appliance with a 110-volt outlet can damage the appliance and pose a serious safety hazard.
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.
