🔍 Key Concepts

• In a DC motor, torque depends on the interaction between the magnetic field polarity and the armature current direction • Think about what happens to torque direction if you reverse both the field and armature at the same time versus reversing only one of them • The difference between changing the circuit configuration (series/parallel) and changing the direction of current in a winding

💭 Think About

• If you reverse the current in both the field and armature together, does the direction of torque change or stay the same? Why? • What specifically must be changed in the motor circuit to make the rotor try to turn in the opposite direction? • Do series and parallel connections by themselves guarantee a change in rotation direction, or do they mainly affect voltage/current distribution?

✅ Before You Answer

• Clarify which action actually changes the direction of current relative to the magnetic field • Check which options merely change how components are connected (series/parallel) without necessarily reversing polarity • Identify which choice(s) would leave the motor still trying to turn the same way, even after the modification
