So I have the following transformer
Is their a particular name for the kind of transformer I have above? I've learned the right side middle is called a center tap, and is used for some weird signallying things in engineering and I don't plan to use it. It's the left part that concerns me...
Thank you. Sounds like I could have them watch a spring oscillator and have them measure their disk rotation speed for different slot numbers. Didn't know the hole was so they could keep spinning the disk at constant speed, though it still may be tricky for them.
What kind of lab activity would you use an Adjustable Hand Stroboscope for?

Would it purely be a qualitative activity? I can't imagine you can do anything really quantitative...
I was reading about the Tusi couple and read it "as a solution for the latitudinal motion of the inferior planets, and later used extensively as a substitute for the equant". Since the Tusi couple is related to plotting out an ellipse, did Nasir al-Din al-Tusi already discover the laws for...
That's why I suspect there is some noise cancellation going on. The FFT jumps around when I speak into the microphone, but if I hold a constant humming tone it quickly dies out. The resolution of the FFT seems pretty bad as well, which was why I was using a tuning fork as a calibration...
I was trying to incorporate this lab into the course, but when I try using a tuning fork on the FFT/Spectrum Analyzer app I can't get a well defined frequency reading. I tried doing the same thing on an opensource FFT app and had the same issue. I am thinking most laptop microphones these days...
I have been seeing interference and diffraction problems involving the double slit and single slit equations that ask for things like the "highest order maxima" or minima, which I have learned are basically found by setting the angle to 90 degrees. My question is are there any real world...
How many electrons can you remove from a solid substance before it breaks down at a chemical level?
Thinking this through myself, you can create positively or negatively charged objects to a degree, especially with a metallic conductor that can tolerate a loss of charge at the cost of the...
So to answer the question about the symmetry of -1/x, a function is origin symmetric if EITHER
For every (x,y) on graph, so is (-x,-y).
or
For every (-x,y) on graph, so is (x,-y).
Is the function -1/x an odd or even function? Is it origin symmetric? For a function to be origin symmetric, must it lie in the 1st and 3rd quadrant or can it lie in the 2nd and 4th quadrant? I suspect it is odd and origin symmetric, but I don't know if I am missing some fine math...
So I know a transistor is built to amplify or multiple an input signal using a base voltage. Are there such transistors that are analog? That is the output voltage is amplified depending on the base voltage? If so, is there analogously a transistor that divides instead of multiplies? That is...
I'm beginning to build a large collection of papers for my research and it is getting bewildering trying to navigate them and collect their citation information. Right now I keep making a text file in each directory with the citation information of each paper and their file name. Is their a...
Homework Statement
A plane is tangent to the surface of a sphere. You then tilt the plane at an angle theta along one axis, causing it to begin passing through the sphere and splitting the sphere's volume into two regions. I claim the volume of the hemisphere the plane has just passed...
