I am studying full-wave rectifier now.
here is the circuit that I made and then I connected oscilloscope between K and L.
As I've learned from the classroom, this circuit has to make full-rectified signal
However, when I measured the voltage between point K and L, I got this result.
I've tried to think what is the problem here, but I can't figure it out.
Is it kind of related to floating ground?
I really don't know what's the problem here.
Can you help me please?
thanks ahead.
and sorry if I sound like rude…I am studying English as well…

As you surmised you can't easily look at the signals on a scope if the AC source is referenced to ground.
You need to get a floating AC source, for example a secondary on a transformer. The your scope ground can connect to point C or D and measure the voltage at the other points such as G and H.
