Diode current can be expressed by an equation called diode current equation. The current equation depend on dark saturation current, the charge of an electron, externally applied a voltage and a constant. We also provide a calculator for the diode current equation.

## 3 Methods of testing a diode with multimeter and oscilloscope

Testing a diode with a digital multimeter in two ways, diode testing portion, and ohmmeter. A diode test is considered passed if it shows low resistance/voltage drop on forward bias and high resistance/voltage drop in reverse bias. A diode curve tracer uses an oscilloscope for VI characteristics graph.
