    RC Circuits and their uses

    haha wowwww. this ISNT HOMEWORK. Its an random inquiry. It was not assigned, hence I used the word "challenged." jeez. whats the point of this forum if people dont discuss the issue and rather the process of bringing up the issue. some people really just need to take a step back and think about...

    RC Circuits and their uses

    We are studying RC circuits in my physics class and I'm just curious as to what they are even for? My instructor challenged us to go find 5 uses for RC circuits and I am stumped. I cant even find any on google. Anybody know of any?

    Line integrals

    id love to correct you but im somewhat stumped as to what you mean.\ I am only aware of using the ftc of calculus to caluclate a line intergral with two points but if it works this way then awesome.

    Curl Test for vector fields

    the curl test is a test to find if a vector field is path independent by taking the partial derivative of F1 and F2 of a function F with respect to x, for F2, and with respect to y, for F1. Basically im havin trouble finding 3 facts to incur about this F after the curl test.
