🔍 Key Concepts

• DC motor braking methods (dynamic braking vs plugging vs regenerative braking) • Effect of connecting armature and field across a resistor after power is removed • Difference between starting connections and braking connections for DC motors

💭 Think About

• What happens to a DC motor mechanically and electrically when its power supply is removed but its terminals are connected across a resistor? • Does the resistor connection cause the motor to speed up, slow down, or simply sit idle, and why? • Which of the listed options specifically describes a condition that occurs AFTER the motor has been disconnected from its supply?

✅ Before You Answer

• Verify which option refers to a braking or slowing down process rather than starting or reversing • Check which methods (starting, reversing, heating, braking) would logically involve using the motor as a generator feeding a resistor • Eliminate any choices that clearly apply only when the motor is being started or reversed under power rather than when it is disconnected
