Dear Darryl, people like you are the reason I will always want to share the knowledge I acquire, just like you're so generously doing in your videos.
I also wish to tell you that it is refreshing to still know there are still people who happily share without being obligated to. Genuinly thankful.

[@JordanEdmundsEECS]

Good video, concisely explains something I was having so much difficulty with.

[@arbythirtysix9996]

Beautiful. Thank you for your efforts in explaining this massively important concept for us electrical engineers.

[@OfficialRichWojcik]

Your voice is better than Ambien.

[@josephmazzulla646]

great video. I'm studying electronics . I'm 86 years old.

[@NetscapeGuy]

Thank you! My professor was horrible. Great basic examples!

[@Wickedgoose2]

Thank you very much for this video, very helpful!

[@reemal9945]

Thank you very much for this video!! It's really helpful.

[@yrmomsuncle]

glad you did that extra example was wondering what you do with three resistors in series. thanks!

[@aTribeCalledCasey]

By the way, the link on your website to this video actually takes you to your first video in the subject. Not a big issue but I thought you would know.

[@user-fu4td7vp4f]

Thank you so much.
your clip is very helpful for me.

[@emile7436]

Great explanation

[@Muraxan]

thanks a lot your video was really helpful to me :)

KVL/KCL will also show the direction of the sources, 'whichever you are using, Voltage or Current' thus determining whether you add or subtract......if that is any clearer.

[@DarrylMorrell]

@DragonsKing91 You always need to use KVL to get the proper voltage across the two sources. KVL will let you know whether to add or subtract the voltages.

Darryl Morrell thanks

[@Symphony2212]

Thank you so much!

Hi! I have a question.
I have a Arduino that can output 5v and 3v.
I have a Nintendo 3DS that runs on 1.8v.
I need to Arduino to send between 0 and 1.8v to the Nintendo 3DS Analog Stick to control it.
Do I hook up two Resistors: R1= 3.2k Ohm and R2=1.8k Ohm to the 5v signal wire from the Arduino?
Does this guarantee that I will only send 0 to 1.8v max from that wire? [using PWM analogWrite(0-255)]?

[@ravinkumar9748]

Thank you V good information sharing...

[@oguzdeveli2159]

thank you master.

[@renaissancemanman]

Thank you!

[@KonigK1ngs]

have you done a video with multiple branches of resisotrs in parallel? thats what i need help with cheers

[@muhammadziaulislamarsalan1392]

Thank you sir

[@jumantosardionpanjaitan3844]

if we want to make a circuit voltage divider for measuring high voltage ac, whether it can use a regular resistor? or is there a high voltage resistor?
thanks for your helping....

[@0xalbic]

you sound exactly like the dad in modern family

[@lajoyapreciosadeDios]

Hello I'm trying to figure out how I would figure the number of resistors needed when they are all the same and you know the output voltage and the input voltage

[@chiefj9767]

I nearly doozed off to sleep

[@noungouamaik6913]

Hello! That was an amazing video. I was able to understand the voltage divider much better thanks to it. However I still have a question. Does the voltage divider works for resistors that are connected in parallel?

[@orvillebebe9123]

Noungoua maik for parallel connections, the voltages are equal.

[@noungouamaik6913]

Thank you!

[@araibirshad7991]

dude , when you have multiple resistors in parallel , the voltage drop across each is the same :D

[@gohan100100]

True dat. True dat

[@aTribeCalledCasey]

Would like to know. ***

[@codyharper7790]

What if R1 cannot exceed (any number) voltage ?

[@codyharper7790]

Cody Harper And your given all the resistance ........ (except the total resistance)

[@bharatelectricals3766]

thank

[@ShadowWalker8]

Just solve for the dam current . you just made the whole dam provlem more complicated then want it needs to be

[@arashghm1992]

honestly i get confused ALOT when im trying to work out this formulas! |:

[@Tino2o9]

Examples are too easy

[@Holmnielsen-]

I don't see how this is different from KVL.....

[@SwapnilSood]

Its same thing just this method is short and like a formula whereas KVL is a concept and not a formula

[@Holmnielsen-]

Ok, thanks Swapnil!

[@SwapnilSood]

No problem :)

[@SynthTony85]

Can this approach be used if there are parallel resistors?

[@HiteshKumarTiwari1604]

Sir aap so ke ude hai kya ,itna dheere kyo bol rahe hai
