in electrica systems we deal with quantities greater than 1
amp or 50 v and while we deal with quantities lesser it
becomes an electronics system.......
i dont know the exact limit of current and voltage that
distinguis between the two, but if you have noticed then in
your electronica lab you will not find any device that
operates on current or voltage greater than 1 amp or 50 v
respectively.

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
