    100w into 2Ω = 50w into 4Ω = what into 6Ω ?


    I'm trying to remember the function rule for power vs impedance.

    anybody help me out?

    Using an amplifier putting out a constant voltage that would generate 100 watts into 2 ohms, will generate 33.3 watts into 6 ohms. The forumula for watts based on an applied voltage and a given load resistance is voltage squared divided by resistance.

      V = I x R

      P = I x V = I^2 x R = V^2/R
