Chapter 1, Problem 13E Step-by-step solution Step 1 of 1 The voltage gain of voltage amplifier without load is, = (Since is not exist) The voltage gain of voltage amplifier with load is, Calculate the output resistance of the amplifier. When a resistance = kΩ is connected to a load, the output voltage is decreased by Substitute 0.8 Therefore, the output resistance of the amplifier, is
