NONSENSE PRINCIPLE :
“These are not the cars that move but the cables”
SENSIBLE PRINCIPLES :
1. The amount of load that cars can carry is directly proportional to the potential difference (voltage) applied to drive the motors and also to the capacity of cables.
2. The speed of running cars is directly proportional to the load they are carrying and to the applied potential difference (voltage) to drive the motors.
BUT, the maximum potential difference that can be applied depends upon the designation of the motors…
