An amplifier provides 10.5 V output under unloaded condition. When a load of 10-ohm is connected at its output, the voltage drops down to 0.5 V. Find out the output resistance of the buffer that is to be put between the amplifier and the load so that the output voltage across the same load would be 8 V. Given that the input resistance of the buffer is 4 K-ohm.
