# Currents and Charges

Currents and charges data are supported for triangles and wire segments and can be requested from CADFEKO or with the OS card.

## Currents on Triangles

The currents and charges data for triangles are provided as follows:
           VALUES OF THE CURRENT DENSITY VECTOR ON TRIANGLES in A/m (no averaging)

2.744E-03  100.59    2.768E-03  2.630E-03  2.850E-03
The current density vector $J$ in the complex form is given at the position (X, Y, Z). The last three columns indicate the value for the surface current density in the three vertices of the triangles.
Note: The value of the current written in the .out file will be affected if averaging of the currents is de-activated in the OS card. If averaging is requested, the average of the current at the vertices of all three adjacent triangles is shown.

## Charges on Triangles

If the current is requested, the charge on each triangle is also written to the output file. Only the charge is given as the position of each triangle is the same as written for the currents.
          VALUES OF THE SURFACE CHARGE DENSITY ON TRIANGLES in As/m^2

Triangle            SIGMA

5    4.02388E-12   56.35

## Currents on Wire Segments

The current on the segments is written as follows:
                    VALUES OF THE CURRENT IN THE SEGMENTS in A

Segment centre                               IX             IY             IZ

Note: In the above table the spacing between columns and the number of significant digits were reduced to facilitate rendering the rows as single lines of data.

## Charges on Wire Segments

If the currents on segments are requested, the charges are also written to the output file as follows:
          VALUES OF THE LINE CHARGE DENSITY ON SEGMENTS in As/m

Segment               Q
number         magn.      phase
1    1.32488E-11  -90.69
2    4.30863E-11 -120.06
3    6.83730E-11 -125.06

## Currents and Associated Data for Voltage Sources

For every voltage source the current at the feed point is determined and therefore the impedance and other related parameters as follows:
