I know digital meters read effective voltages and currents values in an ac circiut so what voltages do analog meters read?

average,paek to peak or maximum or effective

@bwd111

I'm puzzled that you raise this question in another guise when there was a lot of related material on your other thread concerning your debate over analog meters. What further insight do you need?

I searched and searched this forum and google as I always search before I ask due to we live in a microwave world where we are in the right now generation so a search before ask is always faster.

You never answered the question: "What was the debate about?"
My mistake I my fault I posted this twice first time for using fourms. The debate was on what type of voltage does an volt meter and ammeter read in an ac circuit. effective, peak to peak,maxium or average voltage. I know electronic meters read effective but unsure what the analog meter reads in an ac circuit

That's why my boss told me as well but There was nothing on google on this subject. Its a very tough question that google refuses to answer.
It's not a tough question it is just not something simple enough to cover in two paragraphs.

If, by "electronic meters" you mean digital meters, then it is not always the case that they read effective voltage for AC waveforms. I don't know about the cheaper meters today, but a decade or two ago most digital meters were "average responding" just like the typical analog meters. The computations necessary to do True RMS responding were more that was practical in a cheap meter. You knew if you had a True RMS responding meter because they very proudly said so right on the front of the meter, sometimes in several places.

Well the correct answer was avergae. Between the 4 choices of effective,average,peak to peak and max. The correct was Average

The correct answer according to who?

It is demonstrably not correct, since entire categories of analog meters respond to the RMS value.
