Which outcome occurs when a large DC motor experiences armature circuit sparking?

💡 Explanation

Increased radio frequency noise results because the armature circuit sparking generates broad-spectrum electromagnetic energy. The mechanism is Electromagnetic Interference or EMI. Therefore, interference rises; rather than optimizing, lubricating, or perfecting commutator efficiency at this condition.
