The Direction of Electric Current Flashcards
How did Benjamin Franklin investigate the nature of electricity?
He flew a kite during a lightning storm.
What did he decide?
That when describing electricity, the charge moves from the positive terminal (excess of electricity) to the negative terminal (deficit of electricity) of the source of electric potential.
What actually happens in an electric circuit?
Electron flow
What is Electron Flow?
Electrons from the “-“ terminal to the “+” terminal in a circuit.
What is Conventional Current?
Charges move from the “+” terminal to the “-“ terminal.
What was the Conventional Current convention of describing electricity entrenched in? But then what happened?
Science; But approximately 150 years later the electron was discovered.
What became clear?
That what actually constituted an electric current in a metallic conductor (such as a wire) was a flow of negatively charged electrons from the negative terminal to the positive terminal of the source of electric potential.
What is this aforementioned method of describing the direction of electric current referred to?
As electron flow
