Small Grammar Correction

In the Fuses Chapter in the DC Volume there is the following sentence

Quote:

Neither fuses nor circuit breakers were not designed to open in the event of a person getting shocked

This sentence has a double negative and thus reverses the meaning of what I beilieve the author intended it to say. I believe the correct saying would be

Quote:

Neither fuses nor circuit breakers were designed to open in the event of a person getting shocked

All I did was remove the word "not" highlighted in bold above.

In the "Factors Affecting Capacitance" chapter in the DC Volume there is the following sentence that I believe is a bit too vauge and abstract

Quote:

PLATE AREA: All other factors being equal, greater plate gives greater capacitance; less plate gives less capacitance.

I think it would read much better the following way, changes highlighted in bold.

Quote:

PLATE AREA: All other factors being equal, greater plate area gives greater capacitance; less plate area gives less capacitance.

I found another tiny typo, thought I would just post it here rather than starting a new thread.

In the "Practical Considerations" for Capacitors chapter the following sentence has a typo marked in bold

Quote:

Polarity: Some capacitors are manufactured so they can only tolerate applied voltage in one polarity but not the other. This is due to their construction: the dielectric is a microscopically thin layer if insulation deposited on one of the plates by a DC voltage during manufacture.

In cased you missed it, the if should be replaced by an of

Another typo in the Inductor Chapter under "Practical Considerations". Typo highlighted in bold

Quote:

Equivalent circuit: Since inductor wire has some resistance, and circuit design constraints typically demand the inductor be built to the smallest possible dimensions, there is not such thing as a "perfect" inductor

Not should be replaced with no

All About Circuits > Volume I - DC > Chapter 16: RC AND L/R TIME CONSTANTS > Voltage and current calculations

Quote:

The rise and fall of circuit values such as voltage in current in response to a transient is, as was mentioned before, asymptotic.

in should be and

Hi SiegeX!
Thanks so much for pointing out these mistakes. I'm going to let Dennis or Tony approve them first before I fix them here, as they are maintaining the book.

Thanks again

Im glad to be of help, it's the least I can do for such a great free resource. Have said that, here are two more I found in the same chapter:

All About Circuits > Volume II - AC > Chapter 3: REACTANCE AND IMPEDANCE -- INDUCTIVE > Series resistor-inductor circuits

Quote:

If we were to restrict ourselves to the use of only one form of notation, the best choice would be polar, because it is the only one that can be directly correlated to real measurements.

Change added in bold

Quote:

Across voltage across the resistor is in phase (0o shift) with the current through it; and the voltage across the inductor is +90o out of phase with the current going through it. We can verify this mathematically:

Extra "Across" needs to be removed.
