A voltage amplifier (not necessarily an op amp) has a gain of 100 V/V when its output is left open-circuited. However, when the amplifier’s output is loaded with 1.0 kΩ, the gain is only 85 V/V. The same voltage amplifier has an input impedance of 10 kΩ. If the amplifier’s output is left open-circuited but the source driving the amplifier has a Th´evenin resistance (that is, a source impedance) of 150 Ω, then the gain will be less than 100...

Draw and explain the gain frequency characteristic of a resistance–capacitance-coupled amplifier. Reference should be made to mid-band frequencies and to cutoff points. An amplifier has an open-circuit voltage gain of 800, an output resistance of 20 Ω and an input resistance of 5 kΩ. It is supplied from a signal source of e.m.f. 10 mV and internal resistance 5 kΩ. If the amplifier supplies a load of 30 Ω, .
