🔍 Key Concepts

• DC motor armature circuit behavior and what an "open" connection means • Typical causes of mechanical or thermal damage to armature windings/commutator • Difference between protective devices (like breakers/resistors) and actual damage to the winding

💭 Think About

• Which option describes something that would physically stress or damage the armature windings or connections, rather than just changing how the circuit is protected or operated? • Does an open armature connection come from a device opening the circuit intentionally, or from a failure in the winding/commutator itself? • For each choice, ask: does this condition tend to overheat or mechanically damage the armature conductors/commutator bars?

✅ Before You Answer

• Identify which options are protective or control devices versus conditions that cause damage • Think about which condition would increase temperature in the armature area and possibly cause insulation failure or broken connections • Eliminate any options that mostly affect external circuitry instead of the armature winding itself
