    Function generator output oscillations in an RLC circuit

    Certainly, I detailed the set up of the SG and scope in my original post, and attached my LT SPICE simulation which has the circuit. I'm not sure what kind of probe I have, it's just a cheapo one I got at the school store. But it was set to have 1X attenuation I think its called? However, I'm...

    Function generator output oscillations in an RLC circuit

    Sorry, i haven't nailed down my terminology.. By output I mean the oscilloscope's measurement. And input is the FGs output.

    Anything you wish you knew/glad you knew at the start of your education and/or jobs?

    I'm working on a time machine and I'll be taking messages. :D I was actually just curious, I suppose I would tell my 6th grade self that yeah algebra is useful. I still learned it all, but a bit too begrudgingly.

    I think you have to dictate punctuation. My coworker always ended every sentence she spoke into her phone by saying "period"

    Function generator output oscillations in an RLC circuit

    Hey guys, (This post is a bit rambly, read and answer at your leisure) Right now I'm covering RLC circuits. I had a series RLC circuit connected to an oscilloscope and function generator. I used a BNC T splitter on the output of the FG and a BNC to BNC to connect the FG to the scope. I then...

    Quick equivalent resistance question.

    Haha you caught my mistake before I could make it, I was going to treat the supply like an open circuit. But I need to treat it as a short

    Quick equivalent resistance question.

    *cough cough* R1 means nothing when the supply is 0. Req is R2+R3

    Quick equivalent resistance question.

    So learning about inductors at the moment, and I came across this resistor arrangement and I'm not sure how to solve it. The inductor which has been excluded from the diagram connects between point A and ground. I need to determine the resistance "seen" by the inductor, but I'm not sure how...

    Well there's your problem! Can you help me identify this part?

    Awesome thank you! I'm curious how you tracked it down

    Well there's your problem! Can you help me identify this part?

    TL;DR I need to replace what I think is a diode labeled AXJ82 So my brother pulls his Blofeld synthesizer out of his clothset, saying it turns on but does not output audio. I say okay and begin to take a look at it. He points me to a 5K Ω resistor which commonly goes bad. I notice there is...

    Switching a transistor with "body voltage"

    Update, connecting the grounds of my PS and arduinos together makes the transistor turn off when the base is connected to a "0V" analog output. Which makes sense, my laptop's ground must be higher than the power supply. So everything that happened with the 2222A makes sense. However the...

    Switching a transistor with "body voltage"

    So I was messing around with a S9018 http://vakits.com/sites/default/files/S9018%20Transistor.pdf In which 3 V from my PS was connected to the collector and an LED was connected to the emitter. The LED was then connected to the - of the power supply. I connected the base of the transistor to...

    Whats the point of the Op-Amp in this D/A converter

    Thank you for the clarification

    Whats the point of the Op-Amp in this D/A converter

    I've been tasked with building a digital to analogue converter for my class. Like so: https://www.electronics-tutorials.ws/opamp/opamp11.gif It needs to have 5 volts in on the inputs and 1 2 3 4 on the output corresponding to pressing 1 2 3 4. I understand how to do this, but I don't see why I...

    "Spikes" on an uncalibrated oscilloscope probe, and an RC circuit question.

    Sorry for the lack of response. Been busy. Thank you for the response!

    "Spikes" on an uncalibrated oscilloscope probe, and an RC circuit question.

    Sorry, I don't really know how to google this. So I was using an oscilloscope in my school's lab today, our lab procedure had us clip our probes to the scopes 1 kHz calibration wave form. I know this is to get rid of what I've heard being called "batman's ears" see my picture. This picture is...

    Will you become a ghoul from climbing a radio tower?

    Will you become a ghoul from climbing a radio tower?

    Fallout references aside, my friend showed me this video of these base jumpers who climbed a transmission tower: And it got me thinking, is the radiation coming off this tower strong enough for it to be unhealthy to be that close for the time it'd take to climb?

    What is your troubleshooting sequence?

    Makes me think I should chase problems with a voltmeter not just a continuity meter, thanks for the input.
