An amplifier rated at 30 w output is connected to a speaker whose impedance is 10Ω.
1. If the power gain of the amplifier is +42dB, what is the input power required to obtain the full output from the amplifier?
2.If the voltage gain of the amplifier is 60dB, what is the required input voltage if the amplifier is to produce its rated output?
