Electrical Diagrams For Electronic Tests


1) Testing A TRIAC


To test a TRIAC simply we have to place as shown in the image and press the switch. If the lamp is turn on this means that is in good condition

2) Testing A Zener


To test the Zener simply we have to place as shown in the image and measure the voltage. If the voltage of operation is correct then it's in good condition the Zener.






ZENER Tester

5) Dimmer


An economical way to control the speed of an AC motor is using a dimmer. If you want to control the speed of a fan this is the circuit are you looking for.By changing the value of the potentiometer, amending reason the capacitor charge.This allows control can be the amount of current flowing to the load and so the power therein, is to be consumed.
