0 a plan of an electrical or electronic circuit
When the start button was pressed to set the first automatic train in operation it went backwards because the circuit diagrams were incorrect.
It is often the first type of bipolar transistor young hobbyists encounter, and is often featured in circuit diagrams and designs published in hobby electronics magazines.
These are, of course, equivalent to the proof nets of linear logic, but labelling the planar areas is clearer with this type of circuit diagram.
The reader ought to compare the circuit diagram to the pasting diagram above, to help see how the typing works.
Figure 3 shows the corresponding circuit diagram.
A circuit diagram would display the inputs according to their sign with respect to the output when a particular input is greater than the other.
The equation above, however, relies on modeling the electrode, cells, and their surroundings as an equivalent circuit diagram.
This is reminiscent of a circuit diagram with a voltage source shown and the wires actually completing a circuit.
