The braking resistor in dynamic braking is connected to the armature leads.

• A. Field windings
• B. Armature leads
• C. Stator
• D. Rotor

Answer: (B)

Dynamic braking uses the machine’s own rotational energy to generate electricity. When power is removed, the armature acts as a generator, and the generated current needs a path to flow so that energy is dissipated as heat. Placing the braking resistor in the armature circuit provides that path directly, so the generated current passes through the resistor and the energy is converted to heat in the resistor, creating braking torque that slows the rotor. The magnetic field is typically kept energized separately to sustain the field, but the braking path itself is in the armature circuit. If the resistor were connected to the field or another part of the machine, the generated energy wouldn’t be directed where it’s needed for effective braking.
