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: The definition of the ampere changes with effect from 20 May 2019. After that date 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: After 20 May 2019, 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!’
