D. External circuits

​

Answer 1

Answer: I hope this helps you please mark as brainliest answer

The current increases to a maximum, which is determined by the series resistor, after which it stabilizes and remains constant over a wide range of applied voltage. The breakdown is either due to the Zener breakdown effect that occurs below 5.5 V, or impact ionization that occurs above 5.5 V.

Answer 2

The current in a Zener diode is controlled by Zener diode resistance.

• Voltage regulators, reference elements, surge suppressors, switching applications, and clipper circuits all use Zener diodes. The load voltage is equal to the diode's breakdown voltage VZ.

• When the diode is conducting, the series resistor limits the current through the diode and decreases the surplus voltage.
• Zener diodes are commonly employed as voltage references and shunt regulators in tiny circuits.
• When a Zener diode is reverse biased and coupled in parallel with a variable voltage source, it conducts when the voltage approaches the diode's reverse breakdown value.
