Description: Examples of elementary diode circuits: forward and reverse biasing, breakdown voltage, voltage stabilization with Zener diodes. The program may be used as well as calculator of the essential circuit values, as for electronics training (as exercise generator). Possibility to chose the diode model: ideal, practical or complete (consideration of internal diode resistances). Application and electronics help texts included.

Free Pascal features: Loading images from files. Using a second form for data entry. Hiding and showing controls as needed; changing controls' caption and position during runtime.
