You're writing the instruction manual for a stereo amplifier with a maximum output of 100 W. The amplifier can be modeled as an emf in series with an 7 2 resistance. Part A What should you specify for the loudspeaker resistance to be used with the amplifier? Express your answer to one significant figure and include the appropriate units. ? R= Value Units Submit Request Answer Part B How much power can the amplifier deliver to a speaker with half the optimum resistance?
