Hey guys,
I am having trouble with a problem. I would like to derive a formula for some parameters (resonance frequency, Quality factor, Wcl and Wch)
Normally, you will use a general second-order function for a second-order RLC circuit (which is easy to derive). However, my circuit is much more...
Much like my last thread, I have another homework problem in which I must solve for a current value using nodal analysis. I've attempted the problem using some techniques to visualize the circuit from the last forum post and felt confident in my answer, however it is again incorrect and I'm not...
What does pull up mean? In circuit examples, for example for a ESP8266 chip, pull up is connecting to Vcc through a 10kΩ resistor. Why 10k? How is this value derived?
I have seen two separate cases of pull down. One connects to a 10kΩ to ground while another connects directly to ground.
Hope...
as I want to calculate the transfer function of circuit that is meant to generate source current using an Op amp as control loop, I need the gm and r0 of the mosfet(to determine the transfer function of the Op amp current source with nMOSFET) here is the picture of MOSFET with showed parameters...
Hello. This may be a simple problem, but I'm struggling to obtain the resistance R found in the figure below.
First what's throwing my are the two voltage sources. I'm used to seeing these present in op-amps, but the way they intersect is throwing me. I'm not sure how to determine their...

Hello I'm from South Korea. I need help about this circuit.
Picture 1 is typical connection about IR2101
this is my circuit that i designed.
I want to know how it works. I want to know about working principle.
1. HIN = High, LIN = High -> Output "U" = ?
1. HIN = High, LIN =...
Dear Friends,
I am working in an Electronics Manufacturer service (EMS) and we do PCB assemblies for Automotive products (ABS).
We are getting many field failures due to components burnt issue. Mostly like diodes, ASIC, MCU and FET components are getting damaged/burning in the field.
Whenever...
I'm working on a project in NI Multisim i simply cannot find two Balance ICs: HY2210 and HY2213 or their replacements or some circuit or SPICE models.
I've searched ewerywhere I could think of and no sings of such.
Please, help me.
Hello,
I would never thought I could not understand a circuit made out of diode but here I am.
1-the first circuit is two diode in series, when i measured the voltage between the them I found it half the voltage of the source which is not logic for me!!! as there is no current flowing through...
Hi!
I have this exercice and I'm stuck. The answer is 6.12∠144.78° (A) but I got 7.061∠-48.017° (A) can someone detect the error ?
=> 7.061∠-48.017° (A) [ ? ]
Thanks
Hello,
I was found the node's voltages of the circuit and I want a confirmation. Can someone verify using a software ?
This is my try: https://docdro.id/AontV5p
The circuit:
Thanks.
The question is asking what the resistance of the first resistor is (which has been labelled as 0 ohms on the diagram). I am told 20v drops across the first resistor and i am given the value of the other resistor. Now both of the methods I am sure I've done correctly but I'm getting different...
I'm confused a little bit here. The answer that I found is different from the "official", which is V2=9.218∠-39.8° , V3=8.799∠164.97° and the Voltage of depended source is V3-V2=17.598∠152.29° volts.
Ηere is my attempt:
V3-V2=3.88∠68.618° volts and the "official" is V3-V2=17.598∠152.29°...
