The 10V Zener diode is acting as a Noise source. Other two resistors are connected for current control. The 4.7uf Capacitor is working as a filter capacitor. The circuit needs fairly high voltage to ...

The first step to test a zener diode is to identify it among other components on a circuit board or a schematic diagram. Zener diodes are usually marked with a Z or ZD symbol, followed by a number ...

Using this simple Zener value evaluator circuit and a known-value zener diode, you can find the breakdown voltage value of any zener diode. The circuit is divided into two sections: zener evaluator ...

Zener diodes are special types of diodes that can regulate voltage across their terminals when they are reverse biased. They are widely used in circuits that need a stable and precise reference ...
