A good explanation of reverse polarity and the use of diodes as surge protectors; though I wish he would talk more about the other type of element that could be used instead of fuses.

This video deserves 1M views. Youtube must recommend this video to all people.

Thank you so much you helped me alot i don't understand anything in the class but i was always studying culculus here and today i got the results and i got B thanks i don't know your name but i wish i knew it 🙏🏽

[malekalshareef]

Your videos about circuit analysis saved me in my exam today :) thanks so much, I just wish that you would cover more complicated practice problems for computer engineering students

[simonburke]

Great video; I see you suggest a fuse on the negative terminal, is there a reason to do with this particular rig? Just curious because I'm used to seeing them on the positive side :)

[alikaampo]

Thank you for your video, It is much clearer than others.
My question is that is it possible to use resistor other than fuss.

Many thanks.

you are amazing person, mochas gracias

Thank you so much. This helped me a lot.

Thank you for this great video. I learned a few things. I was wondering if you Know if using a MOSPEC F12C20A and its pair F12C20C or, the U30D20A and its pair U30D20C That are used for rectifiers would work. As you know no matter how you connect the power source ( as long as it is not connected to the commons ) It would only pass positive in one direction to the load. I don't know too much about voltage loss so I am hoping you can tell me if this is worth the effort. I already have the MOSPEC F12C20A and its pair F12C20C.

Why it go through D3 not D4 although they are the same (the current flow go to positive sise od D3 and D4)

[nuraisyahsamsul]

If we reverse the polarity of the diode, what changes can be seen in vout in half wave rectifier?

[Axel-jvwb]

I think some devices has fuse and diode inside

[tommorrow]

this is good info but your electron flow is backwards, current flows from negative to positive and through a diode against the arrow neg - ----<|---- + pos. in all your examples your circuitry is correct but your current flow is incorrect.

im.here because i killed and entire array of 40 tp4056 modules during a massive dumb donkey attack lol
