Current Flow in Circuits

There are two basic ways to indicate current flow in circuits.
  1.  Electron Current Flow
 
 
 
In electron current flow ELECTRONS flow from negative to positive.
This type of convention is often used in chemistry.
 
  1. Conventional Current Flow
 
In conventional current flow Current flows from positive to negative
This type of convention is used in physics, electronics, and computer engineering.
 
We will use conventional current flowin our circuit analysis.
