Mastering Complex Circuits: A Guide to Parallel and Series Resistors - DC To Daylight

[@charliejg]

Wow! That was a seriously fun flashback to electronics school, which for me was in the early 1980s! The video also reminded me of the problems we had to do to simplify logic circuits. Back then, almost all of the instructors were former military tech guys. The 8085 microprocessor just came out and op amps were all the rage! LOL! I left that career behind in 1988 when the company I worked for was sold and I went off to college for a teaching degree. I just retired after 32 years of teaching, mostly in an elementary school computer lab. My electronics career helped me land that job. Of course, back in 1994 when it was created I was pretty much the only one "crazy enough" to want it. For me, it was a dream job. One funny note is that to this day I can still recite the infamous mnemonic device for remembering the resister color code. Another gem from the military folks!! Thanks for the trip down memory lane!!

Ha, well you're bringing back memories for me. My first microprocessor was the 8085A, yes the A version - a whopping 3MHz! I recall punching in hexadecimal instructions into a keypad to make lights blink. Man, that would be a good project to actually show how things like a program counter, stack and registers work. After years of analog in school, it was nice to get into the guts of a microcontroller. I always found it interesting how "mechanical" the timing waveforms looked on a logic analyzer.. This could be a good demo. Thanks for the comment!!! -Derek

@@AmRadPodcast Yup, you could program with the whole op code set because it was so small. You could watch the buffer states change and watch for ALE to go low! But, it was state of the art in 1983! LOL!

Great gideo I qm currently in high school learning these types of circuits and their applications, this video definetly helped me understand them better.

[@AmRadPodcast]

That's great to hear! Electronics was my favorite class in high school - awesome that you have the opportunity. Glad I could help! -Derek

The classic voltage and current dividers!

Excited to the next episode of this series 🤠.

[@pierrelocas]

Great Explanation, thanks !!!

[@AmRadPodcast]

Thank you for the feedback! -Derek

[@doctorrusty6494]

Great explanation/reminder of fundamentals in a concise and clear way. Great job, Derek! P.S. Yeah, I do those calculations from time to time for my own sanity, when troubleshooting or prototyping - better to spend some time on calculations rather than blowing up all the freshly bought LEDs 😅 I usually use a spreadsheet for more crowded circuits - in the same form like the tables in the video, with power ratings caclucated too. 🤓

[@chematijerina]

This video is great for refreshing the knowledge on electronic circuit analysis.

You should have showed the RATIO formula when looking at various parallel resistor branch with the resistor values to know the Ratios of current by just looking at the resistor values. Make a part#2 YT lesson about parallel resistor branches using the Ratio formula. Measuring Ghost Voltages in energized wires harnesses or multi wiring conductors the Ghost Voltage phantom voltage is based on the wire length + inductance or capacitance coupling which is a Parallel Branch. If the energized wire has 120VAC and the 2nd wire is non-energized but has a ghost voltage/phantom voltage of 80VAC, 120VAC -80VAC = 40VAC that is loss. The question is why is the ghost voltage/phantom voltage 80VAC and not at 120VAC? and why is there a difference of 40vac?

What did you learn in college? Electrical engineering or electronics engineering?

[@dwagner6]

I’m gonna suggest that the video producer uses the siunitx LaTeX package to easily get the right italicization on units in these equations. 🤓

[@AmRadPodcast]

I usually use a LaTeX variation to create the more "complicated" formulas.. and for the simple algebra, stick to the more on-brand font. Maybe I'll do purely LaTeX in the future. Let's see! -Derek

Don't you think "mastering complex circuits" is misleading given the (albeit good I'm sure) content of this video?
