Excellent video — one thing missing (the one thing I wanted help on, unfortunately). You know those little dots you sometimes see on the transformer(s) on a circuit diagram. I know they have something to do with indicating the winding direction. But, I wanted to get the exact meaning.
Thanks right, the power in, is equal to the power out, there is a little loss of course in the secondary/s. If you have more than one secondary, it is still the power in, is equal to all the secondaries power total.
why is current decreasing in the secondary coil when we do a step up transformation, does that mean that the current will increase if we do a step down transformation, does power (in watt) change from input to the output or it will remain the same?
Great video!! I’m pretty sure a transformer in the charging base for my cordless hair clipper has died. On the bottom of the charger it says 120V 60 Hz 65W. The battery itself is 4.5v how would I choose a replacement transformer to match?
This dude’s video’s are sooooo informative! You can tell he’s an old timer who’s been in this field for many, many decades. Thanks for posting your knowledge for posterity’s sake!!! Take care! NA5M.
8:00 so only when the coils are stacked on top of each other, opposite direction goes from in phase to out of phase and same direction goes from out of phase to in phase???
Right. same number of windings, BUT when you had them sitting side by side, you had the second oscilloscope at one setting. When you had one inside the other you adjusted it. what was the ratio between the settings? was the second demo (one inside the other) a 1:1 ratio on the scope? I want to know voltage going in and going out on each demo ( or you best ratio guess)
@wcemichael
Its the same number of turns with the meter and the oscilloscope. But if the they were set up or down, the electron flow direction is still the same, but the voltage levels would be different.
very good. what I want to ask is. do you have the same number of windings in each coil? when showing the lower meter readings were the settings on the machine steped up or steped down or set equal as the first meter?

I did a video on that, I’ll send it to you.

The primary side looks like a short circuit. It’s just a wire connected from POS to NEG without a load. How can this be?

A new base is close to $100. = Also, Radioshack isn’t what it use to be anymore. Thanks though!
AllAmericanFiveRadio says
I think it would be cheaper the get a new charger, I would look online at Radio Shack.

Yes, there is no outside power supply on the primary.

4:36 the current stops flowing thru both primary and secondary?

very good presentation, clearly put across. also neat demo at the end to show inversion.
