@lcamtuf Hi, I think that Fig. 1-5 of The Secret Life of Circuits has a bug. The two Cl- ions are described as having "net positive charge" but I think "net negative" is correct. But am really enjoying it so far 😊

@lcamtuf I think I found another bug, one that's not already in the errata. On p. 118, you calculate the noise of a 10 kHz resistor on a 20 kHz spectrum. My calculation gives 0.129 sqrt(10 kOhm) sqrt(20 kHz) in nanovolts. Plugging in the numbers, I get 1.82 microvolts, not 1.3 as printed.
