##### Reference no: EM13295040

A certain amplifier has an open circuit voltage gain of unity,and input resistance of 1 MΩ, and an output resistance of100Ω. The signal source has an internal voltage of 5 Vrms and an internal resistance of 100kΩ. The load resistance is 50Ω. If the signal source is connected tothe amplifier input terminals and the load is connected to theoutput terminals, find the voltage across the load and the powerdelivered to the load. Next ,consider connecting the load directly across the signal source without the amplifier, and againfind the load voltage and power. Compare the results. What do you conclude about the usefulness of a unity-gain amplifier in delivering signal power to a load?
