5-9 A 230 V shunt motor has a nominal arma- ture current of 60 A. If the armature resist- ance is 0.152, calculate the following: a. The counter-emf [V] b. The power supplied to the armature [W] c. The mechanical power developed by the motor, [kW] and [hp] 5-10 a. In Problem 5-9 calculate the initial start- ing current if the motor is directly con- nected across the 230 V line. b. Calculate the value of the starting resistor needed to limit the initial current to 115 A.

how to solve this?

For the circuit in Fig. P8.52, choose the load impedance ZLso that the power dissipated in it is a maximum. How much powerwill that be?

how to solve the attached question? please explain or give reference where required in the solution.

HANDWRITTEN SOLUTION REQUIRED NOT USING CHATGPT

Please only do part E and F.  Please show your work and be as detailed as possible. Please explain the relationship between K the gain and stability of the system. Also, show how to plot the poles and why they are on either the real or imaginary axis. What is it about the example that indicated that? thank you

Please draw the block diagram for this problem and explain how.  thank you

Please show your work and be as detailed as possible. I would like to really understand the connection between the type of loop, the dampness, and the gain, K.  Thank you
