Please note the following errors/changes for the Third Edition:
Page 34 The answer to Example 2.22 should be '1.992 nF' not '190 pF'
Page 50 In the solution to Example 3.3 'I1 = I3 - I2 = 0' should read 'I1 = I3 - I2'
Page 50 Example 3.2(b). In both furmulae references to V2 should be V1
Page 50 Example 3.3. R1 should be 110 ohm not 68 ohm (also in text on page 51)
Page 69 The equation for the voltage in Fig. 4.1(a) should be v = Vmax sin (2 pi f t)
Page 70 The equation for the voltage in Fig. 4.1(b) should be v = Vd.c. + Vmax sin (2 pi f t)
Page 70 The equation for the voltage in Example 4.1 should be v = Vmax sin (2 pi f t)
Page 76 L-C-R circuits. Series resonant circuit is shown in 4.13(a), parallel resonant in 4.13(d)
Page 77 The artwork for Figures 4.14 and 4.15 has been transposed (the captions and text are correct)
Page 77 Quality factor. The text should refer to Figure 4.16 not 4.19
Page 80 The formula for secondary voltage should be 'Vs = 4.44 f Ns Ømax'
Page 81 The second equation should read 'Pp = Ps thus Vp x Ip = Vs x Is'
Page 81 The turns-per-volt equation should read 'Np/Vp = Ns/Vs'
Page 310 The caption for Figure 17.18 should refer to 'four' not 'our'
Page 325 Under 'A further program' the reference to 'sun' should be 'run'
Page 349 The caption for Figure 19.33 should refer to '20 deg.C' not '25 deg.C'
Page 374 No answer given for 1.11(e). The answer should be 7.5
Page 374 Answer to 1.24 should be 1.01 x 10^6
Page 374 Answer to 2.12(b) should be 540 pF (not 360 pF)
Page 374 Answer to 2.20 should be (a) 90 mH and (b) 16.6 mH
Page 375 Answer to 2.14 is 0.655 J (charge is correctly shown as 20.79 mC).
Many thanks to readers for pointing these out - I hope they haven't caused you too many headaches!
