Why Is My Full Bridge Rectifier Output Still Positive?

Click For Summary
The discussion centers on the challenge of achieving a negative output from a full bridge rectifier circuit. The user attempted to reverse the diodes in their design to produce a negative voltage but found that the output remained positive. Feedback indicates that the circuit diagrams provided do not show any actual reversal of components, leading to confusion. The output waveform remains positive due to the unchanged configuration of the diodes. Proper adjustments to the circuit design are necessary to achieve the desired negative output.

I wanted to make a negativer full bridge rectifier circuit and filter it, so that after it went past the bridge, the output voltage would be full wave but negative. Tried reversing the diodes on the actual full bridge rectifier but doesn't work.

Refer to the diagram on the left,is it correct? My output waveform is still positive.

You haven't really reversed anything at all between the two circuits. They are simply drawn differently.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
