Just a little extra info to help anyone else to remember the two types: P-type stands for "positive" type because the added hole is positively charged, and N-type for "negative" type because the added electron is negatively charged!

this video is so clear and helpful. Thanks a lot

[anasuniverse]

It will be lovely if you make a series about circuit 2 where it's all about ac signal

[quannguyenminh]

Thank you for your video, it's very useful, but I have a question: How can a"hole" conduct electricity? Thank you!

[meguellatisabrina]

well done! very instructive and engaging. may I ask what tool helped for the animations?
