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 ??????????
