| Aug 5, 2015 at 14:21 | comment | added | user42875 | @Agent_L: the stall current is finite and equal to the voltage applied divided by the winding resistance. Almost infinite is really stretching it. | |
| Aug 5, 2015 at 12:41 | comment | added | Agent_L | Remember that motor current draw can go from almost infinite (when stalled) to BELOW ZERO (when outside force is applied, the motor will become generator). No constant resistor can have same voltage drop at currents ranging from infinity to zero. | |

| Aug 5, 2015 at 11:44 | comment | added | Chu | If the load torque increases, the motor current increases, and the motor voltage will decrease due to additional voltage drop across the resistor | |

Rephrased the title to make it clearer
