When we say there is 110V AC, is that peak to peak?

There is no such thing as 'peak to peak'... the voltage is a
function.... is only has one value at any instant in time... it goes up
to 110 V average or rms in 1/120th of a sec, then goes nagative the
next half cycle. The peak is about 170V (rms x sqrt(2))

Eeyore said:No.
It's RMS.

I bet you can't measure it instantaneously.

You sound like a betting man. I'll give you one reading. You agree that
the voltage has only one voltage at any instant? So you can't do it
unless you find the positive peak over a whole cycle, and the negative
peak over a whole cycle. Sort of a job for some signal processing, or a
couple of diodes and caps, or something that will average over 1/60th
of a sec. That aint instantaneous is it?

Nah. If its digital, and I give you one measurement, you get a dot. If
its analog, and I give you one sweep, an instantaneous measurement is
any height of the trace from zero to the trace. So you could measure
the positive or negative peak at that instant, and hope or guess that
the other peak would be symmetrical, but you've lost the bet because it
would take you two measurements at two instants in time to measure two
peak voltages. I win.

Ascribing magnitude to a steady AC voltage IS the issue - fuckhead.
