Half Wave Rectifiers - Practical Demonstration | Basic Electronics

[@hassan5067]

You literally cleared my year old concept that my teachers couldnt , thank you !

[@CircuitBread]

That's awesome, I'm so glad we were able to help!

[@starlapenner]

this was great! I'm a visual learner and this helped so much!

[@nikteckreviewsandtips6082]

Wow, this gives more insight on the functioning of a capacitor and ratings of resistor, thanks, such a great video 👌👌🙌🙌😌😌

[@Dinco422]

Thank you very much for this

[@edgarcalochcampos1930]

wow great quality and information, thanks!

Why is the wave peak 20 volts but the input voltage 12 volts

[@CircuitBread]

Hey Romario, it's the difference between peak-to-peak and RMS voltages. The RMS voltage is 12V, but the peak-to-peak will be considerably higher (20V in this case). If you're not familiar with RMS voltages, they're essential to quantifying AC signals and I highly recommend doing some googling on them. We have a brief intro to RMS in one of the open source textbooks we host on our site: www.circuitbread.com/textbooks/fundamentals-of-electrical-engineering-i/introduction/introduction-problems but you'll probably want some additional info from google.

The bigger the capacitance the longer it takes the capacitor to discharge. R*C is the time constant. Whoever is watching this should know some simple tasks from differential equations and dynamics of electric circuits (non stationary state).

[@CircuitBread]

Yep! We're actually creating the scope on a series about basic circuits that will include RC circuits, but we haven't gotten too deep into that on any of our tutorials yet.

12vrms/.707 is 16vpeak

Cool video! Just wanted to ask one thing: your language about electrical shocks seems a bit too mild... Am I wrong in feeling that 120V AC is far away from simply unpleasant? Couldn't it kill you quite easily? Also, "have somebody next to you if you feel uncomfortable"... Shouldn't you always have someone close-by unless working exclusively with low voltage? This is not meant to be mean, I might also be a bit too careful... This is meant as a question, more than anything else.

[@CircuitBread]

Perhaps I underplayed it because I often overplay it but don't want to come across as crazy. I got a severe electrical shock from 120VAC when I was 7 years old and still have the scars to show for it. I've sometimes wondered if I should do a video telling the story and showing the scars - now after 30 years (wow, February 3rd was the 30 year anniversary of my shock, I am seriously getting old) most people just think I have a weird sunburn pattern when I take off my shirt. I was unreasonably paranoid before becoming an EE and now feel like I'm just overly paranoid since I have a better understanding of electricity than I used to. That being said, when I am working on my house electrical, I just turn off all power, just so I don't worry about it. But when working on this video, I definitely kept people close by.

[@sciencehegewald5367]

@@CircuitBread Sorry you have gone through that... would be a really interesting video, if you feel confortable with sharing more about this! specially for the whole dealing process of with paranoia concerning electrical safety, I am sure I am not the only one that feels unsure about where they stand - too careful? not enough? thank you for taking the time to answer, I am still entering the EE field myself, so I was honestly confused - and also curious

👍👍👍👍

in the United States, mains voltage will Shock you, not Electrocute you. It isn't pleasant, but I have been shocked thousands of times. I have been told that an open, bleeding wound can act like a wire directly to your hart, and that probably isn't great...

Getting pinned by 270V leg of 3phase 480 volts in a lift 20 feet in the air is fun! "SHUT IT OFF! ARHGGGG! KILL IT!!!!!! Just ask my friend😩 Or let your thumb go right across two phases of 480 Volts! That one was me. 🤬 That hurts! Like someone slammed my thumb with a ball peen hammer, nothing tickly about it !
