THE INSTRUMENT FOR TESTING LOW-POWER TRANSISTORS

THE INSTRUMENT FOR TESTING LOW-POWER TRANSISTORSFor its production you will need two capacitors, a resistor and phone capsule (see diagram). Removing the insulation pad under the membrane of the phone parts are mounted directly in the capsule. Check the transistor is connected to the terminals of ALL the circuits. Occurs phone the sound vibrations talk about the health of the transistor. About its amplification factor β can be judged by the intensity of the sound: loud sound — high β, the weak — β low.
