Name the semiconductor device that can be used to regulate an irregulation dc power supply. With the help of I-V characteristics of this device, explain its working.

Explanation

To solve the question, we will follow these steps:

### Step 1: Identify the Semiconductor Device
The semiconductor device used to regulate an irregular DC power supply is the **Zener diode**.

### Step 2: Explain the Zener Diode
A Zener diode is a specially designed PN junction diode that can operate in both forward and reverse bias conditions. It is particularly known for its ability to maintain a constant voltage across it when it is reverse-biased.
