Introduction to Electric Current and Circuits

The video tutorial explains the concept of electric current as the flow of electric charges through a material. It discusses how devices like batteries and generators produce electric current by creating an electric potential difference. The tutorial also covers the relationship between voltage and current, using examples of different battery voltages to illustrate the concept.

How does the voltage of a battery affect the electric current produced?

What are some other ways, besides batteries, that electric potential difference and current can be produced?
