What is the effect of a short circuit on the quantity of air if fan speed is held constant?

When there is a short circuit in a system, it can lead to various effects on the electrical components and performance of fans. In the case of a fan operating at a constant speed, a short circuit might cause the motor to draw more current than usual. This excessive current can lead to increased torque and ultimately influence the performance of the fan blades.

As the motor continues to run at the same speed despite the short circuit condition, the airflow generated by the fan can increase. This is due to the fan's ability to maintain a consistent momentum, allowing it to push a greater volume of air through the system. The fan's design and characteristics also play a role here, as they can enable it to operate efficiently even under stress. Thus, holding speed constant while experiencing a short circuit can lead to an increase in the quantity of air being moved by the fan.

In summary, even though a short circuit generally indicates a malfunction, in this scenario, the quantity of air delivered by the fan increases while maintaining constant speed due to the increased motor efficiency under the given condition.
