Please clarify what you mean to ask.
Simply move the decimal to the left two places: 110 = 1.10%
The three pin plug is grounded (provided the receptacle is wired correctly).
The three things on a plug are the two prongs (for electricity transmission) and the grounding pin (for safety).
No, it is not ok, it is potentially very dangerous because the two-wire cable has no earth with it. The earth wire is an important safety component that comes with a three-pin plug. An exception can be made for certain low-power appliances that have double insulation. This includes TV sets, radios, and table lights provided the mounting is plastic and not metal. These appliances are commonly sold with a twin-wire cable but often with a three-pin plug on the end of it. The three-pin plug in this case often has a plastic 'earth' pin and it is safe to replace it with a two-pin plug.
It is: 3 and 2/5 divided by 3 and 1/7 = 119/110 or 1 and 9/110
You need two hot legs of 110 volts to make 220. While each led is 110 volts to neutral, between the two hot legs you have 220v. You should have two different hot legs of 110, a neutral and a ground to meet code now a days.
There are 3600 seconds in an hour. 110 seconds is a little less than two minutes. 110/3600 is a little over three percent of an hour.
You plug it into the computer for two to three hours
two in the front, three on each side, and three in the back, though one of these is a plug for the back of the camshaft.
110 volts is the standard electrical voltage in the USA, so you will not damage your iron, when you plug it in. If the iron is dual voltage (110/230 volts), move the voltage selector switch to 110 volts before you use it in the USA. However, there are two diffferent types of electrical socket in North America (with or without earth grounding). For safety reasons, I would not recommend using your iron (anywhere in the world), unless the plug has a round earth pin, in addition to the two flat bladed pins.
Need to know the amperage rating of the plug or the NEMA configuration of the plug and receptacle
Usually 5/8 inch spark plug socket.
