Equivalent circuit parallel to series?
How could one determine R2 and C2?
Which IEM headphones for Soundblaster G6?
Hello first Here are the impedance specs of Soundblaster G6 headphone amplifier Output impedance: 1 Ω, Supported headphone impedance: 16 – 600 Ω I wanted to ask if anyone can recommend some good IEM headphones for gaming (PUBG, Apex Legends, Battlefield) (price up to 250€) for my Soundblaster G6. A week ago I tried the…
How large are the conductance values?
Hi, I'm currently working through some exercises, but unfortunately my lecturer hasn't posted any solutions for comparison. Could you please let me know if my results are correct? The following circuits are given: Let's call the upper one 1) and the lower one 2). My results: 1) G = 0.5 [S] & 2) G =…
R vs Z?
Why do we use R and not Z for direct current? You can write Z=R+0, so U=ZxI is also a formula that can be used for direct current? Or are there mathematical laws that prohibit this? Thanks for explaining.
Diagram: Input impedance for line?
Hi, I have a diagram showing the input impedance of the lossless line. This shows the input impedance during a short circuit. Input impedance of the lossless line: short circuit I have three questions that I don't really understand. Can someone explain the answers to me? I'm not really sure what to do. Why are…
How are the angles of the hands determined?
Hi guys, how do the angles of these voltages and currents come about? What are the angles in this example?
Which amplifier?
I am looking for a suitable amplifier for the Universum VTCF-CD4606. What I don't understand is that there are two drivers per speaker, each with 8 ohms, which would mean a total impedance of 4 ohms in parallel, or 16 ohms in series. However, the speaker itself says 8 ohms. So how does this 8…
Does anyone have a completely solved RLC parallel circuit?
I need the impedance of R,L,C, Z, the currents and voltages, apparent, active, reactive power (values as complex numbers), a vector diagram and, if possible, an explanation. Maybe someone has an old assignment lying around and can help me… I have to create one for a school assignment, but I have no idea how. An…
How do I maintain a resonant circuit?
Hello, if you read my last post you know my project. I plan to transmit energy over an air gap of about 2-3cm (up to 2 amps) In keeping with this, I am currently researching and conducting experiments on resonant circuits. I am able to create and modify these resonant circuits by changing the capacitance…
Please help or solve the mathematical problem?
Hello thank you in advance
For which angular frequency ω does the equivalent impedance vanish?
Hello, Can anyone help me with this task? I just can't get any further. given: C1=200 µF; C2 = 200 µF ; L3= 20 mH; L4= 20 mH Task: a) Switch S2 is open, calculate for which angular frequency ω of the applied voltage the equivalent impedance disappears. b) Switch S2 is closed, calculate for…
Impedance and magnitude of impedance?
Hey, I've got this for the impedance = and wanted to ask if that's correct. I also wanted to ask how to calculate the absolute value of Z. I know that the absolute value of z=, but I'm having trouble figuring out what the real part and the imaginary part are. (I think R is…
