[QUOTE=gmakra;12848663]Ok all you electrical neophites. Electricity has three basic measurements volts, amps and resistance.Most of the other terms you hear are combinations of these three. (there is more to it, but I am trying to keep it simple)
Volts is the velocity of the electricity think of it as water pressure.
Amps is the volume of electrons think of gallons per minute.
Resistance is friction.
Power (watts)is the total comsumption of electricity. To give you an idea of what I am talking about lets use a gallon of water. What we are going to do is fill a one gallon container. Now you can use tea spoons of water or pints, quarts any any size measuring device or combination of measuring devices as long as you fill this container to one gallon.
So power (watts) is overall consumption. One horsepower of electricty is 746 watts. It does not matter what voltage nor anything else. Its like a gallon of water its a contsant and to show you this I will show you a couple of simple formulas.

Power
divide
Current(amps) multiply volts
This is how you work the formula to find a missing value. If you multiply amps X volts it will give you power. If you know the power but are missing the amps you then divide volts into power.

Take a 1400 watt blow drier and you want to know how mamy amps it draws you would divide 120 volts into 1400 watts and you will come up with 11.66666 Amps. And if you take that 1400 watt blow drier and divide it by 746 watts you will see that it comes up with 1.8766 horsepower.

Now wire size can create resitance. You would not fight a forest fire with a garden hose since you wont get enough pressure or volume to really be effective. This also holds true with an extension cord, a long thin cord will create alot of resistance cutting down on voltage and amperage making your power tool sluggish it can also make your tool run hot which leads to insulation break down. A electric motor requires 7 time the run amperage to start. So if your toll runs at 10 amps it takes 70 amps to start.

So Scotty the up shot of all this is use a thicker extension cord your saw will probably run better. Also change the blade it sounds like a cheap one thats not balanced.[/QUOTE]

25' 10 gauge industrial cord... no problems there. No problem with blades or balance. It's just slow, but I can deal with it. Ken has the vibrating saw blade.

Did you try a hammer? Oh wait, it's an electrical problem!

Gmakra, o boy I hate math.

P=IE,
P IS power in watts
I is amps
E is voltage

I=ER
Same thing, except "R" is resistance.

I read this again, George, to try and grasp the concepts you presented. I studied it hard... wracked my brain... fretted over it, even, but in the end I come up with the same ending. All that talk about water makes me have to pee! Ooops!! I'll be back in a minute...
