Reverse the probes and check the reading
Connect the MOSFET's drain to the positive probe and source to the negative probe
Reverse the probes and check the reading
If the readi...

OOP is a programming paradigm based on the concept of objects, which can contain data and code.
OOP stands for Object-Oriented Programming
It focuses on creating objects that interact with each other to solve a problem
Encapsulation, inheritance, and polymorphism are key concepts in OOP
Example: A car object can have properties like color, make, and model, and methods like start and stop
OOP promotes code reusability and ma
