Let say you have a logo like this where "B" is a stylized character that is an image.
Is it better to have the entire logo as an image?
or have "B" as an image but "oat" as just text for better SEO?

When pin 9 is on, current goes to the gate of the MOSFET.
Then seconds later the author says "current passing through could damage or destroy the board" and the video show the current is going backwards. If pin 9 is ON, the Gate goes from 0V to 5V the current also halts to 0A. Why would it ever go backwards to damage the board?

Shouldn't voltage drop arrow point to the same point as forward potential barrier to open? Because voltage drop comes from the voltage it takes to overcome the depletion region.

So the guy in the video says we have to double the uncertainties when we use a ruler because you are technically taking two measurements lining up the pencil at the 0cm mark and at the end of the pencil at around 4cm.
1 . Smallest increment = 0.5cm
2. Uncertainty for each measurement = 0.25
3/ Since we are taking two measurements = 0.25 * 2 = 0.5cm
So this makes sense.
But later in the video, for analog voltmeter how does it make sense to say you are taking two measurements just because you are reading the needle between the lines?
With that logic, don't you have to quadruple the uncertainty for rule case because for each measurement of the pencil you are comparing previous and next line of the ruler? I find it very strange.
