I'm trying to figure out how much wattage my X-mas lights are so that don't go over 1000 watts per out side timer device.

Well wattage is Volts times Amps. 120X0.12=14.4Watts

Use P=IV
P = power in watts
I = current in amperes
V = potential difference in volts
Watt = 0.12 x 120
Watt = 14.4
Hope this help
By the way, don't push it to the limit. Always leave some room for the sake of safety!

0.12 amps at 120 volts is 14.4 watts. P=EI Power = e;ectromotive force (voltage) times current (I)

power (watts) = amps (.12) X volts (120)=14.4 watts
so you have 985.6 watts to go

uhh...you can't subtract amps from volts. Watts = Volts x Amps
voltage and current are completely different things measured in different ways.

watts=VxA
120 x .12=14.4 WATTS
