What are overhead power lines made of?
Mostly aluminum because they are ran in free air and that changes their ampacity rating enough for aluminum to be more economical than copper. Gold has a higher ampacity rating than either al. or copper but it is to valuable to leave hanging in the air.
How are resistors classified on the basis of power rating?
The ability of any component part to radiate heat depends partly on the materials it is made from and mainly on its surface area. So, as large-sized resistors have a much bigger surface area than small ones, the power rating of a resistor is made according to the power (Watts) it has been designed to dissipate safely without overheating.
How does the Resistance and Wattage relate to maximum voltage of a wirewound resistor?
The power rating of a resistor is determined by its physical size. The greater its surface area, the better it can dissipate energy, so the higher its power rating. Knowing its power rating and its resistance will determine the maximum voltage that can be applied to it in order to ensure the resulting current doesn't cause the resistor to overheat. This can be determined by manipulating the equation, P = U2/R.
What is the amperage rating of 500 MCM copper conductor?
It depends on a lot of factors. Generally speaking, if the insulation is THHN then the rating is 350 amps. If the insulation is THWN then the rating is 310 amps. The ampere rating for wire depends on the temperature of the environment it will be used in, the insulation rating and the number of circuits installed in a conduit. There are also other factors to consider... like voltage drop in long runs.

Can aluminum 600v wire work a 40 amp breaker?
Wire size is rated by Amperes of current. You did not mention the wire size of the aluminum wire, so there is no way to answer your question. The voltage rating is more a rating of how good the insulation around the wire is.

How can you repair a mark caused by nail polish remover acetone on a polished wood surface?
You will need:600 Grain SandpaperLemon Oil or WaterNo. 0000 Steel WoolPaste WaxMicro Fiber ClothThis process is super easy and super inexpensive!Use 600 grain wet/dry sandpaper. Soak the sandpaper with either lemon oil or water and LIGHTLY sand the area (If the acetone stain is on a large continuous area like a tabletop you'll want to lightly sand the entire area as to avoid the repaired spot sticking out like a sore thumb.) I know sandpaper sounds scary, but 600 grain is so fine it's more like buffing than anything, just don't press hard! LIGHT continuous pressure! Sanding the area evens the wood finish back out and gets rid of the "ridges" or "dull" spots that acetone most commonly causes.Ok, you've made the surface even... now it's time to restore the luster you began with.Dip the steel wool into the paste wax and buff the surface using medium pressure. The wax will be shiny at first because of the amount of solvent in it, but as it dries it becomes hazy. This is the turning point you need to watch for. Right as it becomes hazy (half way between wet and dry), you need to buff it with a micro fiber or LINT FREE cloth to bring up the shine.If you have a table with slats do one slat at a time.If you have a table with a solid surface do it in CIRCULAR sections (like you're waxing a car). Don't worry about overlap. The solvent in the fresh wax will re-soften the hard wax again, so the circular sections will be seamless.Keep up your beautiful new surface with a DIY wood polish:1 cup olive oil1 cup white vinegarSpray or pour the homemade solution on a soft cloth (never spray directly on the furniture) and work it in, wiping with the grain. Right away you will see the luster return to the wood. Make sure you buff in a circular motion using firm pressure.

What year the sonar technician surface rating established in navy?
The Sonar Technician (Surface) rating was established in the U.S. Navy in 1943 during World War II. It was created to operate and maintain sonar equipment used to detect submarines and other underwater threats. The rating has since evolved to include the use of advanced technology in detecting and analyzing underwater targets.
