1(c). Fig. 1(c) shows a public addressing system i.e. a voltage amplifier, its input is connected witha microphone (input signal source) and output is connected with a loud speaker (load). Ifthe voltage of the microphone is 250mV determine the output voltage across the speaker.Assume that the voltage gain of the amplifier A, = 150, the input and output resistanceof are R = 1.5kn and Ro = 1000 respectively. It is also assume that the microphone andspeaker resistances are Rs = 1.0kN and R1 = 1500 respectively.Rs =1.0 kNRo =100 NVs =250 mVR =Vi 1.5kNA, viR1 =vo1502MicrophoneLoud SpeakerEquivalent circuit of a voltage amplifier
