In the world of Electrical Engineering, the concept of "class" takes on a new meaning when applied to the realm of object-oriented programming (OOP). While in traditional electrical engineering, "class" might refer to a category of electronic components or a specific type of circuit, in OOP, it represents a blueprint for creating objects.
Understanding the Class Concept:
In essence, a class in OOP is an entity that defines a set of objects which share the same attributes and processes. Think of it like a cookie cutter: the class defines the shape of the cookie (attributes) and the instructions on how to bake it (processes). The actual cookies, the individual objects, are created from this blueprint.

Practical Applications in Electrical Engineering:
OOP and the concept of classes find widespread application in various electrical engineering domains, including:
Conclusion:
The concept of classes in object-oriented programming is a powerful tool for electrical engineers. It allows for efficient code development, reusability, and modularity, leading to more robust and maintainable software solutions. By understanding this fundamental concept, electrical engineers can unlock the potential of OOP and create innovative solutions for complex electrical engineering challenges.

Task:
Design a class in Python to represent a light bulb with the following attributes and processes:
Attributes:
Processes:
Bonus:
Implement a method called print_info() that displays the bulb's wattage, voltage, and current status.
Example Usage:
python my_bulb = LightBulb(60, 120) my_bulb.turn_on() my_bulb.print_info() # Should display: "Wattage: 60, Voltage: 120, Status: On" my_bulb.turn_off() my_bulb.print_info() # Should display: "Wattage: 60, Voltage: 120, Status: Off"
def turn_on(self):
self.status = True
def turn_off(self):
self.status = False
def get_status(self):
return self.status
def print_info(self):
print(f"Wattage: {self.wattage}, Voltage: {self.voltage}, Status: {'On' if self.status else 'Off'}")
```
None
