    Undergrad Converting Radians to Vector Notation for Simplifying Expressions

    The arc length of a circle is radius times the angle between the two radius legs that connect the arc. Thus dL = R d@ and dF = I dL x B where B and dL and dF are vectors. how can I convert dL = R d@ into vector notation so that I can simplify these two expressions??

    A beginning RC circuit that resembles a wheatstone bridge

    the capacitors are NOT variable nor are they equal. The resistors are NOT variable nor are they equal. There is no amp meter nor is there a voltmeter in the middle...there is only a switch that has been closed. Now, how would you figure out the potential between R3 and R4. Also, the current...

    A beginning RC circuit that resembles a wheatstone bridge

    Everybody knows what a wheatstone bridge looks like. R1 and R2 are on top and R3 and R4 are on bottom and R5 is in the middle of the angled box shape. let's replace R1 and R2 with 2 different capacitors. Let's also replace R5 with a switch. How would you figure out the potential...

    Microchip's PIC microcontrollers

    I like Microchip's PIC microcontrollers. The ATMEL microcontrollers are a bit more advanced, but I am gradually going towards them. Are there other companies you would recommend for amateur robotics engineers? thanks.

    Undergrad Interesting lesson on Wheatstone bridges

    I enjoy learning new things every time I do a problem set. Take the wheatstone bridge for example. Upon my initial observation, I concluded that the total upper electric potential(V1 + V2) minus the lower electric potential(V3 + V4) ought to give the electric potential that exists across the...

    Is Atkins' Physical Chemistry Book Detrimental for Undergraduates?

    Is it just me or do other people think the atkins physical chemistry book is absolutely detrimental for undergraduates? Unless one is sound in their physics, chemistry, and math and the student is using the book as a means to find out other perspectives on chemistry issues, atkins is not...

    lol, a theoretical physicist and astrophysicist while being productive at NASA...lol! unless you've got the brain of Enrico Fermi, that sounds reallllly tough. then again, I tend to think that I'm a theoretical and an astrophysicist. all i need to do is get a job at NASA.

    Calculate the electric field in the middle of half sphere

    ahhh, yes. the infamous half sphere. you can't quite use gauss's law due to the lack of familiar symmetry, and it seems like you must integrate. tell me about the source charge.
