Get your DMM excel spreadsheet to help determin Voltage and/or output watts

[realdragonluv 10+ year member]

I put together the attached Excel spreadsheet where you can calculate either the voltage output with the desired watts and speaker impedance or to determine the current watts given the DMM AC voltage and speaker impedance.

Simply enter the values in the yellow cells and the results will display in the green cells. I hope this helps someone who may be confused with the worded instructions available.

To use this you need to use a Digital Multi Meter (DMM) set to AV voltage setting and hook it up to your amps speaker output.

Heres a good one too....if you didnt know. Voltage current resistance and electric power general basic formulas calculations calculator general electrical pie chart electricity calculation - electrical power formula general ohms law audio physics electricity electronics formula wheel formulas
