## PHYS345 Electricity and Electronics

## Textbook Errata:

The textbook for PHYS345 is *Electrical Engineering for All Engineers*,
2^{nd}ed.,
Roadstrum and Walaver (John Wiley, 1994; ISBN 0-471-51043-2).
Unfortunately a number of typographical errors remain!
Please alert me of any typos that you discover so that I may add them to the list...

Chapter 2

- Page 2, Fig. 2-2(c)
- The labels on the arrows should be interchanged.
- Page 16, footnote
- ...as the work done
*per unit charge*...
- Page 20, Ex. 2.1
- 125,000 BTU is 132 MJ, rather than 131,850 KJ, keeping the appropriate number of digits.
- Page 25, Fig. 2.10(c)
- 20 V should be replaced with 10 V.
- Page 27, Fig. 2.11(b)
- 5 A should be replaced with 8 A.
- Page 35, P2.4(b)
- This problem has serious problems! See my discussion.

Chapter 3

- Page 43, Equation at bottom of page

- 4
*I*_{1} should be - 4*I*_{1}
- Page 59, Second equation from top of page

- First "=" should be "-"

Chapter 4

- Page 91 and 93, Figs. for D4.11 and P4.3

- The inductor should be labeled
*j*3 ohm and
the capacitor should be labeled -*j*2 ohm.
*(Thanks to Celestina Laboy for reporting this.)*

Chapter 4

- Page 125, Eq. 6.8

- The formula for
*X*_{C} should **not** have a minus sign!
It does belong in the expression for **Z**_{C}.
*(Thanks to Rob Horrobin for reporting this.)*

Chapter 9

- Page 263, P9.13

- The data input for the middle flip-flop should be labeled D
_{2}.
*(Thanks to Adam Tanverdi for reporting this.)*
- Page 264, P9.21

- The last sentences should read "Produce all three outputs."

Chapter 14

- Page 456, Example 14.3

- Some copies of the text mistakenly read:

*Find:* a differential amplifier design with a gain of 10...

"10" should be replaced with "100".

Chapter 17

- Page 577, Example 17.1

*X*_{L} = 0.1 ohm, not 0.01 ohm.

Appendix A

- Page 686, Fig. A-3(e)

- The first "+" sign should be "=".
