A 220-volt, 20-horsepower compound motor (long shunt, Figure 21–16A) has an armature resistance of 0.25 ohm, series field resistance of 0.19 ohm, and shunt field resistance of 33 ohms.
a. Calculate the current taken by the motor at the instant of starting if it is con-nected directly to the 220-volt line.
b. Calculate the current when the motor is running if the armature is developing 184 volts counter-emf.

When I reached out to the manufacturer, they asked for the total power consumption the converter would need to handle.To estimate this, I calculated the power requirements for the components that will use the 120 VDC supply: interior lighting, end lights, and buzzers. The breakdown is as follows:- Light Bulbs: 16 bulbs at 10 W each = 160 W- Buzzers: 2 buzzers at 5 W each = 10 W- End Lights: 2 lights at 15 W each = 30 W This results in a total estimated power demand of 200 W.My concern is whether I should request a higher wattage rating for the converter to provide sufficient tolerance and ensure the system operates efficiently without risking an overload.
