Very nice intention, much appreciated!
Now, brace for impact: In 7 minutes from atoms and electrons, to two glasses of water, to solar cells with car batteries and energy conservation, to conductors and semiconductors, to ideal voltage and current sources, to Ohm and Kirchhoff, to superposition and solving simple electric circuits, all backed up by calculus formulae about electricity. Just stating laws and facts, and give some numeric examples. No explanations, and no demonstrations. It looks more like a first page of a cheat sheet from the first year of EE. Nobody can follow all those topics in the video unless the topics are already well known. If the topic are already known, then why watching the video?
1. Who's your intended audience?
2. What prerequisite knowledge do you expect from your audience?
3. Why would one want to watch your videos instead of competitor's videos?
I know, these are harsh words for a first video, and I apologize. No harm intended.
I wish you all the best for your new channel!
Constructive advice:
- Don't jump all over the place. Take one subject only and explain it. Don't just throw a formulae.
- Always assume your audience have no idea what you are talking about.
Always keep your camera on a tripod, or at least a monopod.
Nice editing and montage, good sound, nice and fluent narrating.
