Question
Chapter 32, Problem 1R
To determine
Find the basic safety rule when working with electricity.
Expert Solution & Answer

Answer to Problem 1R
The basic safety rule when working with electricity is to turn off the power.
Explanation of Solution
Discussion:
The basic safety rules to be followed when working with electricity are listed below:
- When hooking up with the standby systems, always turn OFF the power. Do not work with “live” equipment.
- Installation instructions provided by the equipment manufacturers should be read and followed carefully to operate equipment.
- Do not work with wet hands.
- Do not stand on water when working with electricity.
- After qualifying from the electrical testing laboratories, equipment such as panelboards, generators, transfer switches, and power inlets should be installed.
- Do not touch the bare wires.
Conclusion:
Thus, the basic safety rule when working with electricity is to turn off the power.

- Note: You might want to do the last question first because the last question asks you to write some python code to calculate the zeros and poles.

Since the zeros and poles can be complex, this plot is essentially and argand diagram, where the x axis is the real component and the y axis the imaginary component of a given zero or pole. Create a method called plot-poles zeros(num, den) which takes two lists containing the coefficients. Here is an example and the resulting plot. num [1, 3, 7] # yields zeros at -1.5 +/- 2.17945j den = [1, 4, 5, 3] # yields poles at -2.46557, -0.7672143 +/- 0.7925519j plot_poles_zeros(num, den) Imaginary Page 2 Pole-Zero Plot 3 Zeros × Poles 2 1 -2 1 * Real When you write your code you are only allowed to use the packages numpy and matplotlib.
