Hey! Anybody ever told you a preposition is a terrible thing to end a
sentence with?

: And Arf!Arf! still can't explain why the FCC question pool question used

as an example is WRONG.
: RMS voltage is calculated thusly:
: From FCC Element 4:
: E8A11 What is the RMS value of a 340-volt-peak-to-peak pure sine wave?
: A. 120-V AC
: B. 170-V AC
: C. 240-V AC
: D. 300-V AC

Yeah, but that wasn't the history of it. In message

you posted the following:

"120 V * 1.414 = 169.69 Volts.
Learn how to multiply, DROPOUT"

And that little gem illustrates that you can't even get the final
digit in a multiplication to come out (hint: 2 x 4 = 8) and that you
have no idea about significant digits. You SHOULD have used more
significant digits in the square root of two if you wanted to obtain
the peak voltage to five significant digits (169.71). Otherwise, you
should have rounded the number off to the two significant digits used
in the FCC question pool and obtained 170 VAC.

Your faux pas has forever been archived on Google, and you can't
spin your way out of it. Every time you try, I'll repost the
Message-ID of your blunder.
