What is The Difference Between Electron Flow and Signal or Power Flow?

Electron flow in a wire is just one aspect of a circuit. Signal or power flow is another aspect of a circuit. Both aspects are true in a circuit at the same time, and understanding a circuit requires an understanding of both aspects.

Electron Flow is formed by electrons traveling through a wire.

In a circuit, the electrons travel in a circle formed by the circuit. The electrons:

----- Are sent on the first wire from the power source

----- Travel through the first wire, to the load

----- Travel through the load

----- Travel through the second wire, back to the power source

----- Are reused again in the power source to be sent out again in the first wire

That is the electron travel circle of the circuit.

Signal or Power Flow does not travel in a circle. The signal or power travels from source at one end of the circuit, to the other end of the circuit. Even though the electrons are traveling at the same time both from the power source and from the power source, the signal or power flow is always from the source of the signal or power, to the load.
