    Engineering Understanding Circuit Analysis from a Bode Plot

    Homework Statement http://www.wifstrand.se/Albert/stuff/p13.3-6.png Homework Equations From circuit analysis I've found the network function to be H(ω) = -(10^(-4) +jωC1)/(1/R2 + jωC2) (could be wrong) The Attempt at a Solution I don't know how to determine the network...

    Wrong answers to problems in Introduction to Electric Circuits, 8th Ed

    Wrong answers to problems in "Introduction to Electric Circuits, 8th Ed" I'm studying electric circuit analysis on my own using "Introduction to Electric Circuits, 8th Ed, International Student Version" by Dorf and Svoboda (ISBN 978-0-470-55302-2 to avoid any confusion) and it seems like every...

    Engineering Current through inductor in a circuit with a sinusoidal voltage source

    Yes, I see now that at t = 0 (or rather t = 0+ denoting the exact moment the voltage 6 * cos 0 is applied) the current is 0 since the current through an inductor can't change instantaneously, thanks.

    Engineering Current through inductor in a circuit with a sinusoidal voltage source

    Homework Statement http://www.wifstrand.se/Albert/stuff/p7.7-1.png Homework Equations vL = L * (diL / dt). All of the inductors can be reduced to a single 8 H inductor, so iL = (6 / 8) * ∫ cos 100t dt = 0.0075 sin 100t if you integrate from 0 to t. The Attempt at a Solution The formula...

    Engineering Nodal analysis for OP amp circuit using superposition

    I messed up the calculation of the gain: it's a_1 = v_01 / v_1, not a_1 = v_01 * v_1 ... So with your clarification on this (I believe I tried setting v_a to 0 initially but then I tried other stuff haphazardly since it didn't work with my faulty expression for a_1, LOL...), solving for v_01...

    Engineering Nodal analysis for OP amp circuit using superposition

    Homework Statement http://www.wifstrand.se/Albert/stuff/p6.5-9.png I'm stuck with finding v_o1 (voltage over the 10kohm resistor when all sources but the 3 V source, which I've labeled v_1, is set to zero); seems like it should be really simple but I'm missing an equation. Homework...
