# Full-wave rectifier problem

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.

thanks ahead. and sorry if I sound like rude...I am studying English as well...

• If you measure between K and L, you will only get one trace. Did you by any chance measure K to ground and with the second channel L to ground? Feb 27, 2017 at 23:26
