PURPOSE: To generate simply a table of equations satisfying the 1st and 2nd Kirchhoff's laws and the Ohm's law by adding a new table to a table of an initial set circuit overlappingly for the revision so as to complete the table for the entire circuit.

CONSTITUTION: A and B type elements are handled as basic element information. T table as the table 2 is generated by adding the A type element as the procedure to generate the table 4. The new table differs in it that the R2 column of the Kirchhoff's 2nd law table is zero, because the column is rewritten by using the information of the B type element later and in adding the B type element to the circuit, the table 3 is generated overlappingly thereupon as a part surrounded by dotted lines (the type A is given inbetween and the surrounded part is cut off by the said part). Thus, even a complicated circuit is generated by having only to connect the A and B type elements and overlapping the tables repetitively with the process above.
