How to build Transistor Tester - circuit diagram

This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the output power transistors on amplifier circuits.

El temporizador (timer)El temporizador (timer)

Iniciamos el tutorial con un ejemplo real. Arma el circuito de la figura 1. Pulse momentáneamente el suiche y al soltarlo observe el brillo del led.Ahora cambie el C por uno de 470uF/25V y repita el proceso. Concluimos que el tiempo de descarga del C es mayor cuando aumenta su valor en uF. Ahora veamos la carga del C. Armamos el circuito de la figura 2. Con la ayuda de un tester ó multímetro mida el voltaje DC en los pines del C y observe como va aumentando lentamente su voltaje de carga. Aho.......
