Most people think transformer output voltage is fixed — but that’s not always true.

In this video, I demonstrate a powerful and practical electronics trick using two 220V to 12V AC transformers.
By connecting the secondary windings in series, we theoretically and practically add AC voltages and double the output.

You’ll see:

Real multimeter measurements

Voltage calculations

The exact moment theory meets reality

This experiment proves how AC voltage behaves when transformer outputs are connected correctly.

In the next video, we’ll go even deeper — using two transformers to electrically isolate 220V mains while keeping the same voltage level.

If you’re into electronics, engineering, or real-world experiments, this one’s for you.
