    Engineering Nodal Analysis Problem (Basic Circuit Analysis)

    Homework Statement Find v1 and v2 from the given picture. Homework Equations Ohm's law, V=IR Current Division The Attempt at a Solution I tried to use current division. The 6A source split into 2, giving 2A down the 8 ohm resistor and 4 amperes down the 4 ohm resistor. Since...

    Conceptual Questions about Voltage, Current, Resistance and their relationship

    Ah. Thanks Mapes, that helped. Do you mind helping with the third one too? :D.

    Conceptual Questions about Voltage, Current, Resistance and their relationship

    Oh, hmm. I thought that when R_load is 0, they meant that they took away the resistor. I never thought about it that way. The exact wording of the book was "Find the output voltage with no load attached (the open circuit voltage)" and part (b) says "find the output voltage with a 10k load (treat...

    Conceptual Questions about Voltage, Current, Resistance and their relationship

    Oh snaps, I forgot to upload the last image. Sorry =). My calculations for [B] (a) When R_load = 0 V_in = 30V Total R = 20k Net I = 1.5mA Voltage drop across R2 = I*R = 1.5mA*10k = 15V This answer actually does make sense, since the R's are equal and the setup is a voltage divider...

    What is DC offset in an amplifier and how can it be eliminated?

    DC Offset is pretty much what the name suggests - there is an offset from 0V (DC, I assume) to some other voltage, say, 4V. I guess the best way to explain it is when you look at a scope diagram. For example, say you're looking at a waveform that looks like...

    Conceptual Questions about Voltage, Current, Resistance and their relationship

    First off, mad props to berkeman for suggesting Art of Electronics. It's the first textbook that has actually connected with me. I'll be buying myself a copy. Homework Statement Please refer to the images that I've attached below. I had copied down the images from the textbook, since it...
