I have never heard of a 13 amp plug. However, each flood light would draw about 4 amps since you calculate amps by watts / volts. You just add amps to determine total load.
Not simultaneously because the total current must not exceed 20 amps.
If you know the voltage you can calculate the amps. . Ampere I = power P / voltage V .
Amps and volts are not the same, but related by Ohm's Law. Volts = Amps x Ohms. Ohms is a measure of resistance. Given .01 amps you would have to know resistance to calculate volts.
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
In lights theres 3 amps in them
15 amps at 80% = 12 amps continuous. Watts = Amps x Volts.

At what voltage? If you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.
Amps * volts / 1000
Not simultaneously because the total current must not exceed 20 amps.
A #12 copper wire is rated at 20 amps. On an extension cord, unless it has user installed ends, the rating of the three blade cap is only 15 amps. Either way the extension cord should only be loaded up to 80% of the wire rating. 20 x .8 = 16, 15 x .8 = 12.
It depends on which lights get used. A 100-count string of incandescent mini lights runs at 40 watts, while a 70 count of 5mm Wide Angle LEDs is approximately 4.8 watts total. In fact, because incandescent wattage is 80-90% more than LED wattage, the cost to power an incandescent can be up to 90x greater than powering an LED. Calculate Amps by dividing total wattage by 120 volts (US household outlets carry 120 volts) So about .33 for incandescent and about 4 for LED.

12awg will handle about 20 amps, so 10awg should handle 25-30 amps. Keep in mind that length plays a role in wire size selection. In house wiring, a wire run of 50 ft will work for 15 amps at 14awg, but increase the length to 100ft and you should use 12awg to carry 15 amps correctly.
