    Voltage comparator in a photo sensing circuit

    At 2:30 am this morning I realized how silly I was sounding and figured out how the voltages vary. I know exactly how this works; I don't know where I went wrong before. :D

    Voltage comparator in a photo sensing circuit

    Hello, I attached a picture below but I am confused as to how the voltage comparator is comparing the two inputs (I know how a comparator works). The test points are running down to the two inputs but wouldn't the voltage always be identical across them since voltage doesn't drop in a parallel...

    How is the alternating electric potential produced in cyclotrons?

    If the cyclotron frequency is f = (q B)/(2 pi m) this gives a very large frequency for a relatively large magnetic field and for an alpha particle say. If the acceleration of the charged particle across the "dees" is cause by an alternating electric potential (usually in the form of a square...

    What Magnetic Field Would be Generated from this Coil Layout (Picture)

    What sort of field would be generated from this type of coil layout?? This isn't homework, just a general inquiry. (see picture)

    Building a Cyclotron: Learn, Ask and Find Equipment

    Hello everyone, I'm very interested in building a cyclotron as a learning experience over the next year or so and have been doing some reading on what's required. I figure it would be helpful to ask everyone's opinion on materials such as electromagnets, beam detectors, vacuum cambers, etc. I'm...

    Electromagnetic Generator Coil Number Help

    Google is indeed my friend and i have tried searching but no one seems to have a limited magnet source, the designs I've seen use more magnets but weaker ones. I was just wondering if more coils = more power or if there is a optimal ratio of coil to magnet to ensure maximum power output. Thanks!

    Electromagnetic Generator Coil Number Help

    Hello, I am building a generator for a project in my physics class. I have lots of magnetic wire and 6 VERY strong neodymium magnets, their area isn't overly large (I'd say about 1.5x1.5 inches). How many coils would be best for me to make for the stator? I am making a circular spinning disk...

    Find y' if (x-y)/(x+y)=(x/y)+1 and show that there are no points on that curve

    Ok great! Thank you so much! I think I need an ibuprofen and a good sleep now!

    Find y' if (x-y)/(x+y)=(x/y)+1 and show that there are no points on that curve

    Thanks, this is great. You and Dick are life savers! I understand this completely now.

    Find y' if (x-y)/(x+y)=(x/y)+1 and show that there are no points on that curve

    Thank you Dick, my brain is mush at this point. (Been at this for the past 4 1/2 hours)

    Find y' if (x-y)/(x+y)=(x/y)+1 and show that there are no points on that curve

    I see what you're saying, but the question really doesn't have anything to do with the derivative, its just to show the dangers of calculating something if you don't know whether it exists or not. The question is to prove that there are no points on the curve (x-y)/(x+y)=(x/y)+1 I know I...
