Thanks for showing us how you print out labels?

This music is abominable. And explanations about what you’re doing and why would have been most helpful.

Hmm I think I've got it. Doubling the number of turns doubles the output voltage. Since it doubles the voltage, would it also half the amperage? Similarly, would it work in reverse? Where putting x Volts into the 20 turned coil would output x/2 volts in the 10 turned coil, but double the amperage? Great video, I loved the clean easy to follow editing

Yes, correct. The more turns, less the amperage. Turns and voltage are directly proportional. Turns and amperage are inversely proportional.

With a transformer, Power In = Power Out. When the output (secondary) voltage is times 5, the output amperage is divided by 5, or vice-versa as you said using 2 as the example. It all has to do with the ratio of turns on the two coils. There is an old saying, "there's no such thing as free energy"

A battery is a DC power source; transformers operate using AC power sources. The AC can be produced in a number of ways, one of which is by connecting as the load of a transistor that is being switched on and off.

Is this a step up or step down transformer

It depends on where I consider the output voltage is. If I say that the output voltage is the right hand side where I have fewer turns of coil, then it's a step down transformer.

Did you connect the secondary coil to a resistor and read the voltage across the resistor? It seems the volt meter is connected to the coil directly like ammeter. How did it read the voltage?

The voltmeter has a very high internal resistance, so it will measure the voltage difference across any two points it is parallel to.

The iron core that I used is sometimes called a yoke. You don’t necessarily have to clip them together…as long as the two halves are placed next to each other so that the magnetic fields of the primary coil cut through the secondary coil. Then use a voltmeter to measure the input and output voltages.

A ferrite core is not a good choice for the typical 50 Hz and 60 Hz power line frequencies. And the cores in this video would be a poor choice for frequencies above 1KHz, where ferrites would be more appropriate.

No, on a U core or C core such as in this video, the windings can be anywhere. There are performance reasons for not placing the windings as in this video; better coupling of the windings would have had a voltage ratio much closer to the 2 to 1 turns ratio. Better coupling would be achieved by stacking the windings one on top of the other.
