I was playing around with a new amp this morning and I noticed on the back, near the speaker binding posts a label that said:
"4(ohms) 400Watts" then below:
"40 volts RMS"
Now this is stating the output per channel (400Watts @ 4(ohms)), of course, but I got to thinking what the output current would be (I'm funny this way)?
So if I know the Voltage, the Impedance, and the ultimate Power Output for a given load, how do I determine output Current? I seem to remember some formula that went along the lines of: P=(Ei)/R, but using this, the current turns out to be a rather incredible 40-amps, and I know that cannot be correct.
Thank you for helping me with my little brain fart.
