4 Ways to Test a Transistor - wikiHow
2023年11月17日 · To test your transistor, first clamp the black probe of a multimeter to the transistor’s base. Then, touch the red probe to the emitter and read the display to see if the resistance is high or low. Next, move the red probe to the collector, and check that the reading is the same as it was before.
