<![CDATA[This experimental research focuses on verifying the rectification function of the 1N4002 Diode through the analysis of waveforms captured by an Oscilloscope. The study utilized an applied experimental design, where the subject was tested using an AC signal to visually demonstrate the diode’s response under both forward and reverse bias conditions. Data collection involved the observation and recording of the AC signal output waveform for both bias conditions. The results showed that the diode consistently blocked one half cycle of the input signal while passing the other, firmly verifying the diode’s one-way conduction property. A limitation of this research is the lack of discrete numerical V and I data, which prevents the quantitative determination of the Knee Voltage. The implication of these findings is the visual affirmation of the diode's working principle. It is recommended that future research incorporate DC measurements to plot the I–V curve in detail.]]>
