+Vcc 14 R₁ Re G₁ The power amplifier shown is used to drive an 802/32W speaker through the transformer whose turn ratio is 2:1. The supply voltage is 24 volts. Current gain (B) of the transistor is 50. a. How much is the load resistor seen at the primary side of the transformer? b. How much is the maximum peak-to-peak current swing at the collector of the transistor (assume the collector saturation voltage is OV)? c. How much is the maximum sound power possible at the speaker? d. Derive the conversion efficiency n for this power amplifier. +Vcc 14 R₁ Re G₁ The power amplifier shown is used to drive an 802/32W speaker through the transformer whose turn ratio is 2:1.
