    Regarding a problem with Question 24. It was programmed with the wrong answer. AC DC conversion is what I was looking for, not EMI attentuator.

    So, It looks like I'm going to have to void question 24. Seems like the fairest thing to do.

    I hope that means that you guessed the answer the test was looking for.

    Unfortunately, when dealing with electrical power, the two terms are quite specific in what they do.  Even the Oxford Dictionary uses the correct term when defining what a diode does.  You can also reference variable frequency drives and uninterruptable power supplies for the correct usage. For future use.

    I Googled the difference between conflicting terms. Seems like conventional answer is the correct one. Oh well, we'll let the organizers resolve this one.

    balajivan1995 I'm sorry.  That means that you also got it wrong. Disappointed  Hopefully they will fix it soon - and then all of my comments can be erased so as not to confuse other test takers.

    Passed on 2nd attempt.  Answer on #24 is wrong at this time.  Terminology matters.
