Question
Chapter 59, Problem 1SQ
To determine
Write the characteristics of a person who shall operate and maintain electrical machinery.
Expert Solution & Answer
Explanation of Solution
Discussion:
The electrical machinery is usually operated with high voltage and the rotational machines are rotated with high speeds. Therefore, it is required to take much care to install, maintain, and operate the electrical machinery. The improper maintenance of electrical machinery leads to serious and fatal injuries to the person who maintains the machinery.
The characteristics that are required to a person to maintain and operate the electrical machinery are written as follows:
- The person must be a skilled and qualified electrician.
- The person must have a safety conscious.
- The person must be an experienced electrician.
Conclusion:
Thus, the characteristics of a person to operate and maintain electrical machinery are listed.

4v+9v+8v=-3v+6v',-5v,
where vi and vo are the input and output voltage, respectively.
I decided to focus on the magnitude where I do the normalization on low and high pass and have the bandpass as dB(dB(decibel), with frequency cutoff, I manage to get accurate but have trouble controlling the frequency cutoff accurately and the bandbass isn't working properly. As such I need help.My Code:
% Define frequency range for the plot
f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz
w = 2 * pi * f; % Angular frequency
% Parameters for the filters
R = 1e3; % Resistance in ohms (1 kΩ)
C = 1e-6; % Capacitance in farads (1 μF)
L = 10e-3; % Inductance in henries (10 mH)
% Transfer functions
H_low = 1 ./ (1 + 1i * w * R * C); % Low-pass filter
H_high = (1i * w * R * C) ./ (1 + 1i * w * R * C); % High-pass filter
H_band = (1i * w * R * C) ./ (1 + 1i * w * L / R + 1i * w * R * C); % Band-pass filter
% Cutoff frequency for RC filters (Low-pass and High-pass)
f_cutoff_RC = 1 / (2 * pi * R * C);
% Band-pass filter cutoff frequencies
f_lower_cutoff = 1 / (2 * pi *…
