    Circuit analysis techniques questions

    I just want to know if there are ever any circuits where I am required to use voltage division, or current division, source transformation, etc will i ever be required to use them, or can i get by using node voltage and mesh current analysis? i'm asking because i have a midterm coming up...

    Engineering Determine whether each circuit element is a source or a resistor

    Ah, thanks. That makes a lot of sense. So h, c and e are sources, and the rest are resistors?

    Engineering Determine whether each circuit element is a source or a resistor

    Homework Statement In the circuit as shown in Figure 4, there are three independent sources and five ordinary resistors. (a) Determine which of the circuit elements are sources and which are resistors? (b) Determine the value of the resistance for each of the resistors...

    Choosing the Right u to Integration by Substitution

    i don;t have a specific homework question. i have a sort of conceptual question instead when integrating by substitution, how do i know what to choose as u? for example integral of z^2 / (1 + z^3)^(1/3) dz i am suppposed to choose u as 1+z^3. any other value for u won't give me the...

    Expressing pendulum acceleration in terms of theta and its derivatives

    does that mean that what he posted above was integration? i didn't get that because we haven't covered that in calc yet. i'll go over it again and try to get it

    Converting 0.E from hexadecimal to binary

    Homework Statement convert 0.e to binary Homework Equations The Attempt at a Solution the method the teacher taught for numbers less than zero was multiply by the desired base. then take the whole number and write it down as part of the converted number and drop it. ie 0.8*2...

    How do I solve sin x - x/2 = 0?

    thanks. plotting sinx - x/2 is a bit hard so i plotted sinx and x/2 and found the intersection point.

    How do I solve sin x - x/2 = 0?

    i know that the answer is zero, but i might not get full marks if i don't do it algebraically
