Question
Consider the regular household plug-in that takes a two-pronged plug. One of those prongs or holes is called the "hot wire" - it is at an RMS potential of 120 Volts. Don't worry about the meaning of RMS just yet. We'll get to that later but for now you can think of that as a kind of average voltage for the hot wire. What potential does the other prong sit at -- i.e., what completes the circuit?
Select one: Ground, potential difference of the opposite sign to the hot, potential difference of the same sign as the hot, none of the above.
Explanation / Answer
,Ans : potential difference of the opposite sign to the hot,
