The structure of the pulsar magnetosphere is studied in terms of a DC-circuit analogy. We find (1) the pulsar's death results from the ‘disappearance’ of operating points of this DC-circuit, (2) the outer gap is necessary, (3) the kinetic energy flux of the pair plasma wind and the electromagnetic flux are comparable, and (4) for rapid pulsars only two types of structure (a wind dominated one and an outer-gap dominated one) are possible.
