Superposition Principle

Total electrostatic force acting on a charge

Electric Field

A region around charge object where another charged experience force

Potential

Ability of something to develop in the future

Electric Potential Energy

This tells us how much energy a tiny electric charge would have

Alessandro Volta

He created voltage and a physicist

Drift Velocity

Average velocity which charged particles move through a conductor

Drift Velocity

When electric field applied, electron drift from one direction

Electric Current

Flow of electric charge

Conventional Current

This is the standard direction used in circuit diagrams

Conventional Current

Positive terminal to negative terminal

Benjamin Franklin

The American scientist and statesman who established the labels "positive" and "negative" for electric charge, believing that electricity was a single "fluid."

Joseph John Thompson

British physicist who discovered the electron in 1697.

Electric flow

The physically accurate movement of charges from the negative (-) terminal to the positive (+) terminal.

Voltage

The measure of electric potential difference between two points in a circuit; it is the "pressure" that pushes electric charge.

Electricity

form of energy resulting from the movement of electric charges, usually electrons, through a conductor such as a wire.
