7.86 An emitter follower, when driven from a 10- kΩ source, was found to have an output resistance Rout of 125 Ω. The output resistance increased to 225 Ω when the source resistance was doubled. Find the overall voltage gain when the follower is driven by a 10- kΩ source and loaded with a 1- kΩ resistor.
