A fellow did an experiment with a shorted transformer and posted the video on YouTube along with the math. Since it was in Russian, someone else did the translation. Granted, the fact that the transformer is toroidal, and I am assuming that his windings are possibly wound counter to each other, still, I want to understand how he can get reversal of current on his larger coil and an elevated voltage and an elevated current on his smaller coil when a normal step-down transformer should get a smaller voltage and an elevated current on the transformer's smaller coil?
Each resistor, alongside of each coil, is 1.2 Ohms.
His total amperage is 2.8A, and the voltages on each resistor adjacent to each of his coils are ...
Coil of 11 turns: 8.6V peak amplitude on resistor R2.
Coil of 7 turns: 4.0V peak amplitude on resistor R1.
Doing the math ...
8.6V ÷ sqrt(2) ≈ 6.1V RMS (R2)
4.0V ÷ sqrt(2) ≈ 2.8V RMS (R1)
Doing a little bit of Ohm's Law relationships ...
The voltage of R1 ÷ the resistance of R1 = the current of R1, and likewise for R2. So, ...
6.1V RMS ÷ 1.2Ω ≈ 5.1A (R2)
2.8V RMS ÷ 1.2Ω ≈ 2.3A (R1)
Since his total current is 2.8A, then ...
The currents of R2 + R1 = total current. So, ...
5.1A (R2) + (–2.3A) (R1) = 2.8A of total current outside of the transformer.
Does this mean that with his data, the current on the larger coil must be inverted?
What mechanism of electrodynamic theory makes thispossible mandatory?
