    Why does gravity not create resistance?

    If a planet is traveling through space and distorting space, why does it not slow down? If a boat travels through water and distorts the water it will slow down. I guess a better way to put it is why does empty space not resist being bent?

    Are electrons particles or waves?

    Interesting, thank you!

    a wave: http://youtu.be/1zD1U1sIPQ4?t=48s or a bee-bee? http://www.npr.org/2011/05/25/136656087/what-shape-are-electrons-scientists-try-to-find-out

    Question on Ohm's law and motors

    What I meant was.. I was trying to use logic in a round-a-bout way to get them to see my point. They know that every gauge with a specific insulation is rated for a specific amperage. My point was to explain that voltage doesn't create heat, amperage creates heat. If higher voltage drops...

    Question on Ohm's law and motors

    omg, it was a nightmare... We were replacing some fans at a paint facility for a nuclear power plant. The original fans were 240/480 3phase, and we showed up with two 240v split phase fans. Well, rather than just reordering the right fans we decided to just put these fans in and take power...

    Question on Ohm's law and motors

    ok, I get what you're saying, it's not a resistor. Very nice.

    Question on Ohm's law and motors

    I tried an experiment with a dimmer and an amp probe on my bench grinder. What I found wasn't what I expected. I think dimmers are made a little different today, so I'm not sure if what I found was accurate. I was definitely able to make the motor run slower with less voltage, but the...

    Question on Ohm's law and motors

    Well, I came here with the answer I thought was right. Everyone at work seems to disagree. I came to an engineering forum because I figured you guys would know for sure.

    Question on Ohm's law and motors

    wow, good information. So, you're saying if the voltage only migrates a little the amperage could actually go up? Now, would it, let's say, double if the voltage gets cut in half?

    Question on Ohm's law and motors

    variable: a number that isn't constant and resistor is resistor. The motor will draw like.. 8 times the amount of current when it first starts up then less current. So, depending on the speed of the motor the current will change. And if the current and voltage are changing inproportionately...

    Question on Ohm's law and motors

    On a dual voltage motor when you wire the motor for 120 volts you get 14amps and when you wire the motor for 240v you get 7 amps. Why do you need put the stators in parallel or series if the process is already done for you? This is the only way you can get the same amount of output from a...

    Question on Ohm's law and motors

    well, I don't know what you call it, but it has resistance. So wouldn't it be a variable resistor?

    Question on Ohm's law and motors

    My friends were definitely not talking about back emf. I believe there is a HUGE misconception in the trade about how electricity works and it just baffles me. I just got out of apprenticeship school and people that having been doing this work for 20 or 30 years don't seem to have a clue as to...

    Question on Ohm's law and motors

    I am an electrician, and I recently got into some trouble on an issue. We were trouble shooting a fan motor that was rated at 240v and was only getting 208v. The more experienced electricians I was with said the amperage was going up because there wasn't enough voltage. This makes no sense to...
