studiot.....A plane takes off from NY to London. ~2000 mi.
The NY tower starts counting from 1 to 2000, to monitor the flight.
The London tower starts counting from 2000 to 1 to monitor the flight.
The NY tower uses a positive going magnitude to describe the flight. A
positive flight.
The London tower uses a negative going magnitude to describe the flight. A
negative flight.
It's the same flight.
When the NY tower guy transfers to London.......he had better use the new
reference.........or he will never know where the planes are.
It's just a simple matter of knowing how to PROPERLY change your reference.
But charge flow is a lot more than a plane flight(one way action).
Electricity has symmetry and is always balanced. Two way equal action.
Equal, opposite and balanced. Two equal exchanges or transfers.
This means two charge flows.
