You recently shifted in a house, and you found three appliances, A of 900 W, B of 1300 W, and C of 750W, in the kitchen connected to a supply of 240 volts and a circuit breaker of 7.5 A current. Which appliances can be used simultaneously?
a = 1, b = 3 , c= 9
Need answer quick

Problem 5)
A long shunt 600 V, 1200-rpm DC motor has a series field winding
resistance of 0.05 Ω, a shunt field winding resistance of 200 Ω,
and an armature resistance of 0.1 Ω. The machine is connected to
600 V DC source. The rotational loss is 3.2 kW. If the machine
draws a 100 A from the supply, calculate
a. Back EMF
b. Determine the machine’s converted power (or developed power) and
its efficiency.
c. Determine the speed regulation if the machine draws 165 A at
full load.

H(s)G(s) = 30(s+2)/(s^3+7s^2+12s)
In MATLAB, Use the function margin to plot log-magnitude, phase,
gain margin, phase margin. Do not use the function bode.
I graphed it using margin, but how do I just get the phase? I got
the gain margin, phase margin, and the cross over frequencies.
Thanks
