Q1. How to turn an LED On? Explain with design Difference between BJT and FETs Explain Project
Ans. 
To turn an LED on, apply a voltage higher than the forward voltage across the LED. BJT and FETs differ in their operation and characteristics.
• To turn an LED on, connect it in the correct polarity with a voltage source higher than its forward voltage.

• BJTs are current-controlled devices, while FETs are voltage-controlled.

• BJTs have higher gain and lower input impedance compared to FETs.

• Example: To turn on a red LED with a...read more

Q5. Explain oops concepts with real world example
Ans. 
OOPs concepts are used to model real-world objects and their interactions.
• Encapsulation: Hiding internal details of an object. Example: A car's engine is encapsulated and can only be accessed through the car's interface.

• Inheritance: Creating new classes from existing ones. Example: A sports car class can inherit properties from a car class.

• Polymorphism: Objects can take on many forms. Example: A vehicle class can have ...read more
