Drivers in series or in parallel: is the crossover point affected & what else?

In response to the thread initiated by Hooman R on my previous video. Thank you Eduard and Hugo for the superb discussion, here's my contribution to the train of thought.

I hope you find my videos helpful, and perhaps they saved you money and headaches. You can return the favor and the balance in the universe through Buy me a coffee, which is a simple uncomplicated way to donate as low as 2$ to keep this channel as much ad-free as YouTube allows. I understand that YT adds a few ads, on which YT collects ALL royalties (I get none.) Yet, were I to monetize the channel, the number of ads would sky-rocket and would be very disruptive to your viewing experience. To keep my videos as ad-free as possible, I welcome your kind support through Buy me a coffee. I spend a considerable amount of my time (and resources) to run this channel. As I have NO SPONSORS, get NO KICK-BACKS, nor deals of any kind with any manufacturer, your kind support goes a very long way to help me to keep this channel going! https://www.buymeacoffee.com/RealWorl... I appreciate every kind gesture. Also, through Buy me a coffee you can message me, and I prioritize the Buy me a coffee messages. Greetings, János
