Dude, you are an AMAZING TEACHER. I thank GOD for teachers like you, who are willing to post such life enriching content on KZfaq for us to view for the price of an INTERNET CONNECTION. THANK YOU so very much, from the bottom of my heart sir.

So how to we get 0 volts for the Center tap ?

I agree. Dudes a God send in my case i was struggling until i found Gordons work. Like to repay his teachings someday once i get in the field. The fact he offers this for free speaks magnitude of his character.

This guy is the best teacher on youtube.. I thought he was an electrical engineer. He knows way too much to be an electrician lol..all kidding aside,please keep continuing to make these videos because they are absolute gold!

This man has been singlehandedly saving our education from mediocre teachers. Hats off to you. You explained more in 15 minutes than my teacher did in 16 hours of class time

If engineers explain, we get confused (I think they do it purposefully...Or themselves lack clarity). Here, an electrician clarifies everything...Crystal clear...Thanks a lot

Thank you for your accurate content and knowledge. I passed the master electrician test yesterday you really helped me along the way. Just a dumb HVAC guy who is now a master electrician.

Very nice., I’m currently winding some autotransformers for end fed half wave antennas using 43 mix toroids and enameled copper wire. This helped to bring home the “why” of the ratios I’m experimenting with. Thank you for posting!

I would love to see this as a demonstration to compare CURRENT next. How the load current affects the incoming current. I'm sure it's able to be figured out with the principals described here, but the WAY you teach is phenomenal!

Dave, I had to watch your video several times to be sure I was hearing right. Your explanation of the secondary is good but the primary is backward. To decrease the secondary voltage, you have to add turns to the primary. Tapping the primary will raise the secondary voltage. If you tapped the primary down to the same number of turns there are in the secondary, it would be a one-to-one transformer and the output would be 120v. Your formula says it all: to decrease EsubS you have to increase NsuP.

Dave, have you ever thought of doing a video analysis of Ethernet receptacle transformers? I've had to employ them ad hoc in some of my test equipment and it's all trial and error from stuff I bought off digi-key. I wire them onto proto-boards and I just settle with the one that works. Thanks. Love your videos.

hello dave, just found your channel and am watching all of your videos but was wondering if your earlier recordings can be found? on this channel the oldest videos begin with inductance and and in or out of phase. youre a great teacher and so i would also be interested in learning the basics from you. thank you.

Thanks. What makes the center tap voltage equal to zero. Is it inherently zero (if so, why), or is it zero because it’s connected to ground (for example, in the case of a breaker box)? Much appreciated.

@davegordon6819 Жыл бұрын

Quick answer: Because the center-tap, or center point of the transformer, is connected to ground. Longer answer: First we want to recognize that voltage is the difference of potential between two points, meaning that one point on a system does not have a voltage in and of itself, but rather a voltage between that point and another point. I believe you're referring to a three-wire center-tapped system that is used in homes in the United States where the center point on the winding is grounded and the neutral is also tied into that same point. This means that measuring voltage across the whole coil is 240 V, whereas measuring from either end to the center point is 120 V (half the turns of the total transformer yields half the voltage). If ground is your reference, then you will get zero volts at the center point of the transformer because it is grounded, and you are measuring between two points that are at the same potential. Here are a couple links where I discuss a little more about those systems: 120/240 and 120/208 V Secondaries: kzfaq.info/get/bejne/rrOKnq56mtjQlZs.html 120/240 V, In-Phase or Out-of-Phase: kzfaq.info/get/bejne/pLWDjKuG3a7cd2w.html
