Answers

1. A Zener diode is a type of diode that allows current to flow in the reverse direction when the voltage reaches a certain threshold, called the Zener voltage.
2. The characteristics of a Zener diode include a sharp increase in current when the voltage reaches the Zener voltage, and a low forward voltage drop.
3. The applications of a Zener diode include voltage stabilization, surge suppression, and overvoltage protection.
4. Voltage regulation is the process of maintaining a constant voltage output from a power supply, despite variations in the input voltage or load current.
5. An operating point is a specific point on the characteristic curve of a device, such as a diode, that represents the steady-state operating conditions of the device.
