In summary, PL (programming language) is a set of rules and symbols used to write computer programs. Understanding PL is important for those in the field of computer science and programming. There are many types of PL, such as Java, Python, C++, and HTML, each with its own syntax and purpose. Learning resources for PL include online tutorials, books, and classes, as well as practicing and experimenting with different languages. While not necessary, knowing multiple PLs can be beneficial for certain tasks and make one a more versatile and skilled programmer.

R= pl/A
what does p and l stands for?
 
Physics news on Phys.org
  • #2
p is the resistivity of a material(ohms.cm). Every material normally has a set value for it. l is the length of the material.
 
  • #3
thank you
But if i had a distance of 100 km ,do i replace "l" with d and convert it to metres?
 
  • #4
from my experience with this equation(electronic subject) we had "l" in cm, but that was because we had "p" in ohm.cm for example

R = pl/A ----> ohms = [(ohms.cm)(cm)]/cm(^2)
 

1. What is PL?

PL stands for "programming language." It is a set of rules and symbols used to write computer programs.

2. Why is it important to understand the meaning of PL?

Understanding PL is essential for anyone working in the field of computer science or programming. It allows you to effectively communicate with other programmers and create efficient and functional programs.

3. What are the different types of PL?

There are many different types of PL, such as Java, Python, C++, and HTML. Each has its own unique syntax and purpose, but they all serve the same basic function of instructing a computer to perform a task.

4. How can I learn more about PL?

There are many resources available for learning about PL, such as online tutorials, books, and classes. It is also helpful to practice writing code and experimenting with different languages.

5. Is it necessary to know multiple PLs?

While it is not necessary to know multiple PLs, it can be beneficial in certain situations. Some languages are better suited for specific tasks, so having knowledge of multiple PLs can make you a more versatile and skilled programmer.
