The circuit in the given figure is to control the speed of a motor such that the motor draws currents 7 A, 5 A, and 2 A when the switch is at high, medium, and low positions, respectively. The motor can be modeled as a load resistance of 20 mΩ. Determine the series dropping resistances R1, R2, and R3. The series dropping resistances R1, R2, and R3 are Ω, Ω, and Ω, respectively.
You'll get a detailed, step-by-step and expert verified solution.
