10 amps
watt's law----- W=E X I
W=watts
I=amps
E=volts
1 kilowatt= 1,000watts
just divide 1,200watts/120volts=10 amps

If you mean what happens when you connect a 120VAC appliance to 12VDC, the answer depends on the what is inside the appliance. If it uses a power transformer, the transformer will not pass energy to the appliances but it will conduct huge DC currents and burn out or blow it's fuse. If the appliance is essentially a resistance, such as a heating appliance, AC vs DC doesn't matter and the current varies proportionally to the voltage. Induction motors will behave similar to a transformer. Motors with field coils and commutators may run at a reduced speed.

Amperes = Watts/Volts
= 1.2 / 120
= 100 Amps

The answer is 10 AMPS
You can google ohms law and printout the formula as it will always be useful. Also sites like RS & Dick Smith have this formula and more.

The three units are related through Ohm's law.
Power divided by voltage equals current.
You work it out.
