Hey, I want to make a get better poster with led light sticking out of the poster. I found the following LEDs: http://www.play-zone.ch/de/bauteile/led/led-sortiment-mit-180-leds-oem.html . I have very little experience with wiring circuits (did AP physics a while back) and I'm not sure if this...
Hey guys iv got a conceptual question about light in films. When there's and incident ray in medium air which refract in a medium like glass the ray of light is bent towards the normal, and the opposite for the other way around. And to my understanding the normal is just the line perpendicular...
Hey guys,
I have a simple conceptual question: Let's say I'm moving a loop of wire into a constant magnetic field that points into the page. The wire needs to create a magnetic field out of the page to oppose this previous change in flux. The typical question would be which direction does the...
Hey guys, this is just a conceptual question so i don't think the scheme applies? I've got a circuit with a potential difference, when I use the right hand rule to determine the direction of the magnetic field created by the wire of any side of the rectangle, do I point my thumb (direction of...
