In summary, the conversation discusses the use of a center tap transformer and the voltage distribution across its secondary coils. The participants also share their understanding of transformer theory and provide diagrams to explain their points. One participant clarifies the proper symbol for a center tap transformer and explains that there will always be 6 volts across each half of the secondary, regardless of the current being drawn. The conversation also touches on the frequency and polarity changes in a transformer.

I tried to find the option to start a new thread, but I found it nowhere. Anyways, I have two very basic questions regarding center tapped transformer.

1:See this first:http://sdrv.ms/RmHXQV
How does the sine wave of the voltage reverses for the upper and lower half of center tapped transformer?
To explain my question further, at time 0 the sine wave is at the reference line for both parts of the secondary winding. As time passes it is going in positive direction for the top half, and going negative direction in the bottom half. This reversing of the waves enables us to get full wave rectification. But how does the reversing occurs?

I don't understand why the current is emerging from the ground. Can you please explain this?
