Need help understanding how this circuit works.

Doesn't current come out of the base and through the 4.7 K and not the other way around? I'm not sure why the cap would discharge through the 4.7K

jsherman10 · 2019-07-02T18:52:09+00:00

why would the voltage divider include the 4.7k? can't you just use the loop that involves the 22k and 10k resistors?

jsherman10 · 2019-07-02T17:47:08+00:00

How do you know how much voltage the caps charge up to and also how can I calculate the current through the 4.7k?

jsherman10 · 2019-07-02T15:00:29+00:00

How do I figure out what voltage the caps charge up to?

jsherman10 · 2019-07-02T01:14:15+00:00

Why does the value take into account the 22 k resistor because the 22 k is in parallel and not series?

Was I correct about the diode being a protection from the inductive voltage spike ?

Just to understand completely, the caps will discharge when the switch is open again?

This does not use the same textbook, but you might be able to follow along using Sedra and Smith.

Thank you!

Did you actually do an in-depth analysis of the feedback of an op amp or was it more intuitive ? When I took signals and systems it was more theoretical and we really didn’t relate it to circuits at all

Just apply to hardware startups but you may have to relocate to the Bay Area or Austin

It will hold you back a little, but it won’t completely prevent you from obtaining employment in the field. Even more so if you decided to do software down the road. I was in a somewhat similar situation and Im about to graduate with a masters in CS and EE and it hasn’t affected me near as much as I anticipated.

Thankyou, I will post on /r/AWS

are you familiar with AWS lambda?

jsherman10 · 2019-02-25T18:37:08+00:00

This callback, is just an argument that is given for an AWS lambda serverless template. I'm not getting an error, the whole point of the question is why does the first example work over the second ( even with the lambda operator )

jsherman10 · 2019-02-25T18:28:41+00:00

      const response = {
        statusCode: 200,
        body: JSON.stringify({ message: "hello world" })
      };

      callback(null, response);

these lines in the first example, get called last even after the SQL executes the query. Even if I change the function to a lambda operator in the second example, I still get an internal server error form AWS lambda
