Hi
How can I mesure the power(max) of an audio signal which I guess is an alternative current?
I am asking this because I bought an amplifier of 50w and a speaker of 12w. Eventullay, if I supply the speaker with a power 50w it would be broken but I can regulate the power delivered by the amplifier with a little potentiometer but I don t know "how far I can turn it" so I need to know how to mesure the power of a (alternative) current with a multimeter.
Instead of limiting in output power of the amplifier, I think it might use a resistance but I what kind of resistance I should use.
Regards
