Chapter 2

• p 32, Figure 2: only the plot in Figure 2(a) shows v against i; the other two plots show i against v.
• p 38, Figure 12c: + and - signs are missing along the battery; or, equivalently, an explanation in the text is missing that the long line of a battery symbol corresponds to a +.
• p 45--46: replace the text following Equation 15 until the end of the page by the text below; leave out Exercise 5.

  Hence, the energy delivered to the capacitor over an interval of time from to will be:

  

  From this derivation it can be seen that the change in energy only depends on the value of the capacitor voltage at times and and not on the specific voltage waveform in the interval (the voltage variation over time). The instantaneous energy of a capacitor is defined as:

  

  assuming that a capacitor with zero voltage has zero energy.

• p 51: replace the text following Equation 23 until final sentence ``As in the case ...'' by the text below:

  Hence, the energy delivered to the inductor over an interval of time from to will be:

  

  From this derivation it can be seen that the change in energy only depends on the value of the inductor current at times and and not on the specific current waveform in the interval. The instantaneous energy of an inductor is defined as:

  

  assuming that an inductor with zero current has zero energy.

• p 54, last line before heading ``Ideal Diode'': add ``the diode is reverse-biased and'' after ``,''.
• p 61, Figure P23: 25 mA should be 25 mH.
