In this video, we're going to answer the question: Why are resistors used?

This video explains the basics of electricity, including the flow of electric current and its relationship to voltage and resistance. Using a simulator, viewers can see how different materials and resistors affect the flow of current and...

How do transformers work? find out here in this video on how transformers work the basics.

We've learned all about the periodic trends, including atomic radius, so let's put our knowledge to the test! Here we will have to put some atoms in order of increasing atomic radius, and then do the same thing for some ions and their...
