  1. Question why not use decoupling cap to prevent the voltage spikes? Also curious, why no pull down resistor?

  2. Thank you so much. Visualization of this complex topic makes it so much easier to understand!

  3. I seen couple vidoes and you always refer previous videos. As a new person to this channel, I have no idea. I would appreciate if you keep this in mind while making new videos.
