Errata for Introduction to Practical Electronics for Inventors, 2007 edition

• p. 58 - last paragraph, "signal equivalent" should be "single equivalent".
• p. 51 - Example, "100 ohm battery" should be "100 ohm resistor"
• p. 66 - This section has a number of conceptual problems in Figures 2.55 and 2.56, in that the equivalent circuits should be in terms of the galvinometer (the "G" in a circle). The central pane of Figure 2.56 also wrongly has a "V" in the equivalent circuit where the author meant "A".
• p. 75 - The equation for I2 has it equal to VA-IB*R1/(R1+R2). It should actually be VA+IB*R1/(R1+R2).
• p. 168 - Figure 2.159 erroneously leaving j out of two expressions of Euler’s Identity, should be "z = rcos <theta> + r j sin <theta>" and "V = Vo cos( <ohmega>t ) + jVo sin( <ohmega>t )".
• p. 182 Should be "Series Impedance (LC Circuit)" instead of "Parallel Impedance (LC Circuit)."
• p. 472 - Change "Prdicting" to "Predicting" and under "TRANSCONDUCTANCE" change "is gate-source voltage" to "in gate-source voltage".
