🔍 Key Concepts

• Armature current and how it is affected by voltage in a DC motor • The voltage that is induced in the armature conductors when the motor is spinning • How induced voltage relates in direction and effect to the applied line voltage

💭 Think About

• What happens inside the armature as the motor speeds up—does any internal voltage develop that opposes the applied line voltage? • How does this internally induced voltage affect the net voltage driving current through the armature circuit? • Which of the terms in the options is commonly used in DC machine theory to describe this opposing induced voltage?

✅ Before You Answer

• Be clear that line voltage is the externally applied voltage, and you’re looking for an internally induced voltage that partially cancels it. • Recall the standard textbook term for the voltage generated in a DC motor that opposes the supply and limits current as speed increases. • Eliminate any answer choice that does not represent a commonly used technical term in DC motor operation.
