A significantly-expanded ‘Introduction to Electrical Science (2nd Edition)’ was published in 2018.
I would like to draw your attention to the following typos, errors that crept into the book during its production, and to changes that have occurred after the book was published:
Page 3, table 1.3: The alternative symbol for the litre (L) should be a lower-case script form of ‘ell’, NOT the Greek letter ‘lambda’ (λ) as shown.
Page 5: With effect from 20th May 2019, the definition of the ampere changed. You may wish to delete the present definition (expressed in terms of the force between current-carrying conductors). See ‘News About the Ampere‘ elsewhere in this blog.
Page 27: You may wish to delete the present definition of the ampere (expressed in terms of the force between current-carrying conductors). See ‘News About the Ampere‘ elsewhere in this blog.
Page 28: Immediately above the paragraph which starts, ‘For most purposes…’, please insert the following: ‘After 20 May 2019, its value will be exactly 1.602176634×10−19 C.’
Page 29: In the paragraph below the equation for drift velocity, the charge on a single electron should read: ‘160 × 10-21 C‘, not ’16 × 10-18′ C. This, unfortunately, changes the worked example as follows:
This means that the paragraph immediately following the calculation, therefore, should read: ‘That’s an incredibly-low 3448 seconds, or 0.95 h, to travel just 1 metre!’
