4: 10 I'm no electrical engineer but this sounds like the ol buy 1 for 2 dollars or 3 for 5 dollars deal, you could spend the 2 bucks for 1 or get 3 for the 5 dollars but you don't really need or want the other 2, i mean so you spend all the extra energy output to push all that extra voltage to minimize loss but when it gets to the destination your squeezing it waayyy down sooo does that excess get used up? I mean I guess it would if the grids planned out in a way that oh say the output could power 10, 000 homes n it's going to around 9, 800 homes so you know you won't run short if a few of those homes have increased intake for a Lil while but not so much excess that you got 5, 000 homes being powered by a transmission that COULD power 10, 000. cuz the excess that's not used needs energy to supply n keep available but just simply goes unused. Am I making any sense? Honestly at this point I have no idea if I am or not

I am utterly impressed by the exceptional quality of your electrical engineering videos! It's not an exaggeration to say that your content stands head and shoulders above the rest. The meticulously crafted diagrams are a visual delight, making intricate concepts appear effortlessly clear. Your pacing is a masterclass in itself it's neither too hurried nor too slow, allowing me to grasp every detail without feeling overwhelmed.
What truly sets your videos apart is the ingenious use of real-world examples. These relatable scenarios not only demystify complex theories but also ensure that the knowledge sticks in my mind like never before. Your dedication to providing such insightful and practical content is genuinely commendable.

Excellent reference material! One thing I'd like to see an animation description about a transformer's actual primary & secondary coil counts not just the ratio.
Suppose there is a step-down transformer that steps 240VAC down to 60VAC. This is a 4: 1 step down. But the coil count can be any number of turns that match the ratio. It could be 400000 turns primary and 100000 turns secondary or it could be just 4 turns primary and 1 turn secondary. What is happening in these two extremes? Also does the AC line frequency determine the optimal turn count?
No video or tutorial I've seen suitably discusses this critical concept yet it is one of the first decisions one would need to make when designing an actual transformer.

I didn't search the comments and surely a more timely viewer already noted this. At 8: 27 even though you didn't call attention to it you showed an example of how a points ignition operated. The points quickly broke a 12 volt DC supply to the primary windings of the coil causing the voltage to decay and thus have a delta voltage wrt time thus inducing a voltage in the secondary windings. I suppose the modern individual coil packs also get a quick pulse of 12v which provides the delta voltage wrt time to induce the high secondary voltage that will jump the spark gap.

One question that has eluded me with transformers is this.
Let's say you have an RF transformer that is matching the impedance between stages of amplification. The primary side is lower impedance, and also has a Large DC component that the AC signal rides on. My question is if the DC component would get passed to the secondary along with the AC component, or does the secondary only 'pick up' the rate of change in the magnetic field from the AC?

I work with them all the time on vintage arcade/pinball games. Lighting is usually either 6 or 12 v ac, and coils use 24 or 50 volts. Some motors and heavy duty coils run off the household current. They very rarely fail, though new folks sometimes think they do. Your video shows how simple they are with no 'moving' parts, though they can vibrate after they have seen many duty cycles.

that's why we see a sine wave pattern if we connect a 'scope to a power outlet. you're lucky, every time i try and scope my plug sockets my house trips out. the only way i could look at it was by using a transformer to turn 240 into 12, 0, 12 and probing that.

I'm trying to build a tiny ground loop isolator for an audio mixer. Found a video, but didn't know what a transformer was. Now I have a couple ideas on how I might make this work! Thank you!

What determines the amps in a transformer? The amps on primary incoming line? The resistance in a transformer winding? How does the strength or number of the iron magnetic lines of force field play into voltage, resistance, and amperage?

It's taken me many years and qualifications to get the confidence to touch a transformer but I think after this video, I finally feel confident, despite just finishing a domestic installation course videos are always on point

In previous videos you said that voltage is like a pressure higher the voltage means higher the current but in this video you r saying that higher voltage means lower current how it is possible please clear my doubt.

My background is University of Technology, Sydney. My subject is Electrical Engineering. Currently I am in Bangladesh. I often see transformer on an electric pole. They are situated between two poles.

Corrext me if i am wrong TEM, but the example of the European Kettle boiling quicker than the USA kettle is because of the differences in Wattage output of the Kettles (1500W as opposed to 2, 500W)

My only question I still have, is, how is this not a short circuit? I remember trying to make my own transformer in middle school and I browned out my house, so how do you prevent that?

Okay, but I need more than just a simple AC to DC converter.
I need the assurance that whether or not the components malfunction my expensive camera will not be damaged.

It's easy enough to make a DC transformer. It is just like putting a motor next to a generator. just get rid of the rotors. Stator next to stator.

Why can the wire gauge into smaller step down transformers (240v>24v) be less or smaller than the wire supplying power to it?

so basically the principle used by a transformer is, a changing electric field produces a changing magnetic field and vice versa

if you wrapped with a aluminum wire do it still make power or all transformers must wrapped with copper wire to make power

it's a bit overly simplistic to say transformers don't work with DC. what about pulsed DC? what about flyback transformers?

4: 24 would there be a 24% power loss with an 86% transferred energy efficiency? Why is there an 86% loss instead?
