Here are 8 questions you’ve sent in. Rare (at least, up until now) video of James talking unscripted. Questions answered in this video: 1. Why does AC change direction?2. What do home appliances run on?3. Is Analog or Digital More Accurate?4. When do you use Pull-down resistors?5. Difference between LM7805 and LM7812?6. What diode to pick for a motor’s flyback diode?7. Does James draw his own Animations?8. What does “AddOhms” mean?

https://youtu.be/WxJKXGugfh8 We live in a world of analog. Clocks are a great example of how time is continuously changing with nearly infinite precision. However, when you look at a digital clock, there are very specific “digits”. (Get it? Digital… Digits…) Using the analogy of clocks, this TutorialCast explains the basic difference between Analog and Digital Electronics. It ends with a slight twist.
