Braking time in the dynamic braking is the function of _____________(a

1.	Braking time in the dynamic braking is the function of _____________(a) System inertia(b) Load torque(c) Motor rating(d) All- system inertia, load torque and motor ratingI got this question by my school principal while I was bunking the class.My doubt stems from Braking of DC Motors in section DC Motors of DC Machines
Answer» The correct choice is (d) All- SYSTEM inertia, load TORQUE and motor rating Best explanation: In dynamic BRAKING, when brakes are applied the armature is disconnected from machine CIRCUIT and connected to the braking resistor. Now, at this point motor is driven by kinetic energy GAINED earlier, dissipating power in braking resistor.
