power output formula
I built a small audio power amp to drive my computer
speakers. With one channel driven into 8 ohms the PP voltage measured at 1khz was 24v before clipping. With both channels driven it was 20v. I think the formula for power output was ((vpp/sqr 2)**2)/R which would give me 36W one channel, and 25w per channel with both driven. (not bad for a 2n3055/mj2955 pair running at +- 15 volts) Is my math correct? |
