Physics for IGCSE & O level - Magnets And Currents (Section 5 - No. 4)
If an electric motor stalls, what is likely to happen?
The motor will run faster.
The motor will produce more torque.
The current drawn by the motor will increase dramatically.
The motor will stop drawing current.
Объяснение
When a motor stalls, it is not rotating, so the back EMF (that reduces current draw) is absent, and the current can increase dramatically, which can damage the motor.
