SESK: Stuff Everyone Should Know · sesk.info/eng-conventional-current-direction
In a copper wire, how does the direction of conventional current compare to electron flow?
Opposite: conventional current is drawn the way positive charge would move.
- Opposite to the electrons' motion ✔
- The same direction as the electrons
- There is no set convention
Why: Current direction is defined as the direction positive charge would move. In a metal, negative electrons drift the other way.
Huh, didn't know that: The convention dates from Benjamin Franklin's time, before anyone knew electrons carried the current.
Electrons never follow the arrows. They are true rebels of the circuit.
