The braking resistance in a chopper-controlled motor system can be expressed in terms of duty cycle (D) and motor parameters as follows:
Braking Resistance = (V^2) / (2 * R * D)
Where:
V is the voltage across the braking resistance
R is the resistance of the braking resistor
D is the duty cycle of the chopper
This equation represents the relationship between the braking resistance, duty cycle, and motor parameters in a chopper-controlled motor system.
