A 300hp, 240V, 600 r/min motor is required to be stopped with dynamic braking technique. If the nominal armature current is 100A, calculate, (i) The value of braking resistor R if we want to limit the maximum braking current to 150% of its nominal value (ii) The braking power (kW) when motor has decelerated to 200 r/min Assume armature resistance to be negligible for this problem.
