the magnetization curve of a 2-pole, 100V DC shunt motor at 2200 rpm is given below. The armature resistance is 0.12Ω. The shunt winding has 500 turns per pole and its total resistance is 125Ω. Full load current is 40A. Since the motor has a compensation winding, the effect of the armature reaction is neglected. The total rotational losses of the motor (Pfe+Pfw) are 240W : Using the given values;
a) Draw the equivalent circuit of the motor. Find the speed of the Motor at full load. b) Calculate the speed regulation. c) Find the shaft torque and efficiency of the motor.

please answer HW #1: Chapter 1: 1, 5, 7, 9, 13, 15, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 these qustions and show the work too thank you

I need help in fundamentals with this hw. Please your answer must be handwritten and show work. Check the file for questions are really easy ones.

Please answer the following 2 questions, when using AD2, pls use the waveforms app on your laptop.

Design a CCTV system with the following minimum requirements:
Type of establishment: 2-storey Residential or Commercial with parking space.
Floor Area: 1,000 sq.m.
Lot Area: 1,500 sq.m.
Outputs for Submission:
Single Line Diagram
As-Built Plan
Additional Instructions:
Submit a printed output in A3-size paper. (SLD and As-Built Plan)
Attach your DWG file and turn-in your submission.
CCTV layout must be printed in color over a grayscale floor layout.
Use the attached DWG file for the layout template.
Note: The layout template should be .DWG but since I can’t able to upload it I turned it into PDF instead so you may access it by using AutoCAD and turn it into .DWG to further view the template.

here is the circuit lab.
I attached the lab and the template for the lab it might required to take a screenshot of the baord or lt spice I

Q1. Given the following setup code for Timer 2, write an Interrupt Service Routine (ISR) for Timer 3 that uses INV to toggle the LED light connected to Port A, RA5. The ISR should be called Timer3Interrupt. Timer 3 setup: Internal fPB clock is 40Mhz , pre-scalar 1:256
Q2. a) If TAD = 85 * 10-9 (85 ns) Seconds (Assume PBclk-Freq = 40 MHz , [2 Marks] So TPB = 1 PBclk − Freq ), Calculate the ADC’s value. Hint: TAD = 2 * (TPB * (ADCs + 1)) b) Write the following Setup code for the ADC with manual sampling and manual conversion.
Q3a.Write a program using an Interrupt Service Routine that does the following : Waits for a Single High Pulse of 250 ms on Pin OC3. When the High Pulse goes from High to low , it turns ON the LED at Port A, RA3 and the LED then stays on. You will use the Output Compare OC1, Dual Compare mode with a Single High Pulse (OCM= 004). You will use Timer 3 for the OC with a pre-scale value of 256. You need to setup OC3RS and OC3R such that OC3RS – OC3R = 200 ms. We need to convert 200 ms into Timer Clock Cycles. We have Timer 3 with a fpb is 10 Mhz and a Precale of 1:64.
