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

In this DC to Daylight episode, Derek breaks down a relatively complicated series-parallel resistive circuit that you will eventually run into, either in school or on the job. He covers some of the basic tools that are needed to understand circuits like this, such as Kirchhoff's current and voltage laws, as well as the voltage and current divider laws. Putting these tools in your belt will put you in the right mindset to tackle a problem like this, without breaking a sweat on your next exam or weekend project!

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!!

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

The classic voltage and current dividers!

Excited to the next episode of this series 🤠.

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. 🤓

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?

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

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

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

odd enough, I was tough this info in 11 grade high school
