yeah. im pretty confused abt tht. people usually say electrical current flows frm + to -, while at the same time acknowledging tht electron flows in the opposite direction. how is tht?

250 years ago Benjamin Franklin proposed that electricity was a flow of charged particles moving from "plus" to "minus". This was a guess, but it became the accepted model for electricity. He probably also introduced the concept of "ground". We now know that the charged particle is the electron and it actually moves from "minus" to "plus". Unfortunately Franklin's 200 year old guess still influences the vocabulary of electricity and electronics causing much confusion.

Pretty cool!

Hello, An early guess about the nature of electricity suggested that some sort of positive particles flowed from + to -.
This is referred to as "conventional current"
The discovery of the electron led to the realization that electricity is probably a flow of electrons from - to +. This has led to a confusing situation with text books using one or the other or both explanations.
I prefer the electron model.
