We have tried to practise a new style of physics exercises for students, in order to improve the effect of the basic science education in dental school. In this study we designed the application of A/D converter to the voltage-current characteristics of diode in physics exercises. The system is composed of the electronic circuits for both the impressed voltage and the current detection, an A/D converter and a personal-computer. The electronic circuits can generate the ramp waveforms as both the forward and reverse voltages with the amplitude of 0.86Vp and 3.60Vp respectively, and detect the amplified current of diode. The data output in CSV form via the A/D converter were set up in Excel on Windows 98,and then displayed on the CRT screen under program control. This system developed as an educational exercise was successful in producing the voltage-current characteristics curve, within the framework of the voltage resolution of A/D converter.
