    i'm going to do my college level project.so i m having some doubts abt the amplifier and its principles..so guys help me to clear my doubts..
    1.can we use an amplifier as an power generation system???
    2.in amplification , input = gain * output
    therefore, input +_________= output
    3. what is the balancing factor between the input and output of the amplifier? how the gain produce in the amp?
    4. for ex: in current amplifier: input = 1
    output=1.5
    gain=1.5 ; thn how the gain would be produced ??????????

    Amplifier is a circuit. So Input power is always lesser than the output power.

    It uses external power from DC source to increase the magnitude of INPUT SIGNAL.


    Amplifier can not be used as a power generation system as efficiency is always less than 90% for effective operation
