Question

DISTINGUISH BETWEEN ZENER DIODE AND RECTIFIER DIODE USING MULTIMETER

Answer 1

Explanation:

Although they are both called diodes they have very different uses. ... In this circuit they have used a 5.1V Zener diode, if you were to use a multimeter across Vout then you would measure 5.1V, all the other voltage is dropped across the other components in the circuit, in this case, a 1K resistor.

Unlike standard diodes that are employed in the forward direction, Zener diodes are designed to be used in the reverse direction. The reverse breakdown voltage of a Zener diode is referred to as the Zener voltage VZ, and the current value at this time is called the Zener current (IZ).
