Doc Physics – Transformers are Awesome!
Step up, step down, step all around town. But who’s buying?

The way you ended it was totally AWESOME!!
08:02 I coughed up my chocolate milk.
funny ha ha!
I don’t get it why is the voltage on the primary coil= (-N*the rate of
change of flux wrt time)
isn’t it supposed to be = to the voltage supplied by the A.C. source ???
Why is it with small transformers I cannot have the input with very few
turns? As in certainly if I make a transformer with one primary turn and 2
secondary turns and attempt to apply mains voltage to it, I will make it
explode?
Dude you’re Awesome ! Thank you for the great explanation ..
Wow, this is the first time i actually laugh at a science teaching video,
good job my friend, i subscribed!
You’re awesome bro.
Btw, you should watch your videos in 1.5 speed. I feel like I’m in a vortex
of knowledge when I do.
Old vintage flyback transformers from CRTs are really great real-world
examples of the diagram at about 6:25 for demonstrational purposes, I plan
to use mine when I get around to teaching electronics merit badge for boy
scouts.
Wow, a lot of enthusiasm, it made learning about transformers more fun and
interesting. It was a little bit fast paced for me, but overall it was a
great video!
great !! this was helpful i have a presentation over tomorrow , and i got
the part of step up and step down transformers , wish me luck 🙁 thanks
afain . i subscribed
Even though english is only my second language, I was able to understand
clearly what you said in this video and it really helped me out. Thank you
for these informations!
you are awesomeeeeeee mannnnnn………… i am your fan
I don’t understand why they take the square root of the ratio relating
inductance of the primary to inductance of the secondary √Lp/Ls as well as
the impedance √Zp/Zs. For a step-down transformer: Np/Ns = Ep/Es = Is/Ip =
Lp/Ls = Zp/Zs(ideally). Example: Np/Ns = 687/186; Ep/Es = 16.794V/4.546V;
Is/Ip = 64.874mA/17.564mA; Lp/Ls = 3.0435H/0.824H; Zp/Zs =
956.143Ω/258.867Ω
some adapters use switching circuits – so the time ! power is gated ?
( whether a ups / uninterrupted power supply , or laptop charger ) sets
the final output voltages .
Seriously, of all the videos that I’ve watched from you, this one was the
funniest. Thanks always!!
I see the iron ring on your hand. Can’t wait to get mine. though you should
wear in your pinky finger
LOL!!! Subscribed. Well done my friend, well done.
i get it with full of fun!!! thx doc <3 anyway looking forward for more
videos about magnetism! i have trouble this area. love u
um one doubt, wont there be any back emf ( or the “bad” emf) generated in
the coil, casue the input voltage is always changing with time?
Thank you so much for clearing up the big voltag-small current mess doc!!
Question: as I understand ohms law says that if voltage goes up current
goes up and vice versa, if resistance stays the same. So I guess you can’t
just decide if you want high or low voltage/current? So the resistance/wire
is not the same on the secondary and primary right?
This video was so helpful. Thank you
I tasted a Jim Carry:P . Man you are hilarious 🙂 I laughed very much while
you talking XD ! Man you made smile me XD Thx for your comedic fluency that
narrative XD
I am a high school student for English and I am really thankful that was
helpful .
