A full-wave rectified 32vac voltage without filtering or smoothing
components. Just a bridge rectifier connected across a transformer 32v
secondary (no center taps) without a load connected to the output of the
bridge.

What will my DMM read if it's in DCV mode when connected to this output?

Thanks,
Dave

with no capacitors and a cheap average-reading DMM about 28V

** So more expensive DMMs read *OTHER* than average values on their DC
volts ranges??

Do tell.

If a good "True RMS" DMM is used, will the reading be different?

And can you help "teach me to fish" (show me the math)?

Thanks,
Dave
