Extracted text: Q1(a). The open circuit voltage of a voltage amplifier is 12.5V when its input is connected to a signal source. Assume that the signal source voltage is 2.5V and its resistance is 2.0ka respectively. If the input and output resistance of the amplifier is 5kn and 500 respectively, the amplifier output is connected to drive a load resistance 500n, determine the output voltage across the load.
