    Magnetic field intensity problem

    Hi everyone here, hope you enjoying this summer .. i'm taking ' elements of electromagnetic ' course this summer session and i just have a little question here in the yellow shaded statement shouldn't it be dl = (l/N) dz instead of dl=(N/l) dz ? By the way, it's not a HW...

    Engineering Is the Simulation Accurate? Analyzing an Op Amp Circuit with Multisim

    => Vn = 29/30 v and Vo = 14.5 v => I s = ( Vn - 0 ) / 15k = 64.44 uA I a = ( Va - Vp ) / 1k = -466.67 uA I b = (Vb - Vp ) / 2k = 766.67 uA I c = ( Vc - Vp ) / 1.5k = 22.2 uA I g = ( Vp - 0 ) / 3k = 322.2 uA

    Confused with Omp Amplifier Problem - Part B Solution

    it inverts the left hand amp ,, ( the inverting amp ) . Vo = -12 Vs . my question was : part b says that " assume Vsat = 12 " . Why not 15 ? thanks

    Confused with Omp Amplifier Problem - Part B Solution

    i am confused with this problem , part b : http://img85.imageshack.us/img85/1736/ampe.png my question is : Does Vsat reffer to the right amp or the whole circuit ? or something wrong with this problem ? thanks :)

    Help solving the initial value problem

    when u divide the right side after integrating by , u should also divide the constant too so it should be

    Help solving the initial value problem

    you firstly have to integrate the right side before you multiply it by !
