What are Conductors and Insulators? | Don't Memorise

There are lots of ways to categorise different materials based on their Physical or Chemical Properties. One way is to categorise them based on their CONDUCTIVITY! Based on this property, we classify materials as Conductors, Insulators and Semiconductors. In this video, we will study about Conductors and Insulators. We will see a few examples of the materials in each of these two categories. Watch the entire video to know more!

Conductor or Insulator?

A conductor allows electrons to move freely and an insulator blocks their movement. In this video, I test several different objects to see if they are insulators or conductors.
For example, is a pickle a conductor or an insulator?
I answer these questions by hooking up an electrical current.
Is copper a conductor?
Is wood an insulator?
Plastic Conductor or insulator?
Aluminum Insulator or not?

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything
