for more information on the skipped section at around 3:40 he is talking about how to utilise the right tool for the job, if you only need to apply 1nm of torque then a 5 litre v8 that produces 400nm isnt the right tool. the gearing refers to the ability to change the load while maintaining a speed. if you expect to have more resistance you should use a higher gear ratio (ie 6:1 is more top speed 8:1 is more acceleration) with more rpm

It doesn't matter how slow was the locomotive going - always it took from power line half of maximum current or maximum current depending when motors were conected in series for start and low speed or paralel for speeds over 40km/h

Your videos are very useful to me personally and I find your ability to dig up, refine and present information to be quite commendable. I tip my hat of to you sir. I learn a lot of new things and even clears up or refreshes many concepts I forgotten. Sometimes I use info from your videos to help my students in class, if not, I just directly say to them to see your video on those topics and tell them he explains it better and he is funny too. I watch your videos even if I m not particularly looking for anything. This video particularly is one of my favorites and have watched it may be a few dozen times while just wondering around your channel. So I think you should do those videos especially on the emi filltering. I would love to see your take on the topic as it is one of things that fascinates me more than any other. Anyways Thanks for reading. Take care. :)
