Studying the origin and definition of electricity or electric current is essential to understanding its various applications. Electric current in conductors is defined with respect to free electrons that exhibit random zig-zag motion within the conductor. It is the flow of charged particles, ...
This lesson will explore what electricity is, the types of electricity that exist, how it is generated, and how it is studied.
