How voltage dividers work - Voltage Division | Basic Electronics

[@akulanvn381]

Thank you so much for explaining with actually doing it and showing it physically it helps me alot to understand.

Holy crap! Out of at least 5 videos I watched, yours actually explained the effects of adding a load. I have a last question remaining: Why not use just one resistor in parallel to the load? It would serve as a voltage divider too, but I am not sure about the consequences.

Hey, thanks for the feedback! As to your question - if your load is known and stable, you could totally do that. However, it is a bit more of a challenge because usually you don't know what your load's equivalent resistance is to choose an appropriate coinciding resistor. Or, if you're trying to use it with a something non-linear, such as an ADC reference, your load equivalent resistance will vary when it's taking measurements and not taking measurements. So, you're absolutely right, you can do that! It's just got a couple more challenges to figure out.

fantastic explanation :)

Your videos are pretty good. I will refer my classmates to watch and subscribe the channel. Because we are Electronics and Telecommunication engineering students

Awesome, thanks! Good luck in your studies!

Thanks for explaining. I failed to use a voltage divider to power my trimmer. I realized that the load resistance was changing the voltage, but I thought I was doing something wrong. The way everybody explains a voltage divider is like it's a module that isn't affected by anything else. Nobody talks about how load resistance screws things up. I am a mathematician who loves electronics, I have recently been able to afford to buy some electronics and experiment at home and I realized how complicated things can be. I aced my physics exams but, I guess, I didn't really understand as much as I thought I did. Thanks for the video.

Glad to be of help!

Wow man, you and your channel is really cool. I'm definitely gonna subscribe after I'm done with writing how cool your channel is.

Thanks!

Is good for input to gate of BJT or FET or SCR/thyristor, DIAC?

[@CircuitBread]

Yeah, I've seen voltage dividers used for inputs to FETs and BJTs quite often. I don't recall for SCR and DIACs but I don't see why not in that case either.
