Bridge rectifier circuit:
The voltage drop upon the resistor
is positive no matter the voltage
of the voltage source.
Potential graph representation:
Potential difference of edge R is positive
no matter the potential difference
in the source S.

R
This property in the terminology
of the electronic circuit reads:
the current through the resistor is positive
no matter the current of the current source
The graph is self-dual, therefore
flows manifest the same property:
the flow through edge R is positive
no matter the flow in the flow source S

Another voltage rectifying circuit
Cannot serve also as a current rectifier
The corresponding graph is not
self-dual
