List of errors - chapter 1
Errors in textbook, chapter 1:
Location
Original text
p. 5, figure 1.2-5
“... negatively charged and that “ ‘tis
the earth that strikes...”
p. 16-17, Voltage
Contradictions:
In the text: “... vba is proportional to
the work required to move a positive
charge from terminal b to terminal
a.” [Where b is positive and a is
negative]
Modification
???
“...vab is proportional to the work
required to move a positive charge
from terminal a to terminal b.”
[where a is positive and b is
negative]
In the following definition (top p.17):
“The voltage across an element is
the work (energy) required to move
a positive unit charge from the terminal to the + terminal.”
“The voltage across an element is
the work (energy) required to move
a positive unit charge from the +
terminal to the - terminal.”
p. 20, bottom
The last paragraph doesn’t fit there.
It seams tobe lost and disconnected
from the text.
“Now let us consider an example...
supplied by the element.”
Remove this paragraph.
p. 21, exercise 1.6-3
“... the power plant is shown in
figure 1.6-1a.”
“... the power plant is shown in
figure 1.6-1b.” (Since we are talking
about a circuit that delivers power.)
p. 23, last paragraph
before exampl 1.8-1
“In example 1.12 we use...”
“In example 1.8-1 we use...”
p. 24, example 1.8-1,
Verify the proposed
solution
“... v = 24 V.”
“... v = 12 V.”
p. 27, 3rd row
“... the magnitude of the current is
less than 1 A.”
“... the magnitude of the current is
less than 1 mA.”
p. 27, Terms and
Concepts
“Electricity: Physical phenomena
arising from the existence and
interaction of electric charge.”
“Electricity: Physical phenomena
arising fromt he existence and
interaction of electric charges.”
(More than one charge is required to
talk about interaction.)
p. 30, Design Problems,
DP 1-1
“The current waveform and the
power waveform are shown in figure
DP 1-1b.”
“The current waveform and the
power waveform are shown in
figures DP 1-1b and DP 1-1c.”
