50 amps maximum and 40 Amps continuous. The voltage in this case doesn't enter into the equation. There are some issues to consider when DC is involved with arcing when plugging or unplugging device. You should only do this when power is off.
Look at the back of your fridge and find the plate that tells you how many amps it needs. Once you have Amps you multiply that number by the Volts coming out of your plug (usually 120v) and you will get Watts. So once more: Amps x Volts = Watts
That depends on your router. The current draw of a router (or any other electrical device) can be calculated by: Amps * Volts = Watts If you know any two, you can calculate the third. If (for example) the router draws 750 Watts, and you know that it plugs into 120 Volts, then you can plug into the formula Amps *120 Volts = 750 Wats OR Amps = 750 Watts/120 Volts OR Amps = 6.25 If you would like the answer in volts it would then be about: 120
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.
Electric furnaces are rated in Kilowatts. The following formula will let you figure it out. Watts = amps x volts. For eg. a 10 Kw furnace draws 10000 watts. amps = watts/volts. 10000/240 = 41.6 amps. If your furnace differs from this example, just plug in your wattage and you will have your answer.
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 40 amps equals 9600 watts. One horse power is 746 watts.
In Canada and the United States, wall outlet voltage is standardized at 110 to 120 volts (anywhere in that range is considered "OK"). In Europe - most of the rest of the world, actually - it is standardized at 220 volts.
You may as well ask, 'How many metres are there in a kilogram?'! The ampere is used to measure current, while the volt is used to measure potential difference -they are different quantities, so you can't convert one to the other.

Watts = Volts x Amps x Power Factor To make your calculation you need to plug-in the Voltage and Power factor. The Power Factor is a value from zero to one with one being a pure resistive load.
110 volts
A few small things. Watts = Amps x Volts. Amps = 800/120 = 6.66 amps. Check the amperage on what you want to plug into the generator. If it is over 6 amps the generator will not handle the load.
My understanding is that it takes about 20,000 volts to arc between the two parts of the spark plug and most automotive coil put out 20,000-50,000 volts.
