The amplifier shown below has a variable gain control, using a potentiometer for RE with the wiper ac- grounded. As the potentiometer is adjusted, more or less of Re is bypassed to ground, thus varying the gain. The total Re remains constant to dc, keeping the bias fixed. If a load resistance R₁ of 600 2 is placed on the output of the amplifier, what will be the value of RE for the voltage gain (50)? Neglect the output resistance to of the transistor.
