Curious what the crowds watch over on YouTube? Me neither. I can share what the average profdurgin watcher looks at over on the group’s EM channel, though. Below is a rank-ordered list of the top 25 videos by watch time among the EM lectures, based on lifetime video statistics.
Although not all videos have been on the site for the same duration, a few basic trends are apparent. The time domain transmission line series (TDT) is very popular, likely because there still are not many texts that cover that material comprehensively. The introductory lectures on wave mechanics series (WAV) are moderately popular, as are some of the time-harmonic transmission line (THT) videos. Magnetic materials are popular because there just are not many magnetic materials lectures for electrical engineers.
