An ideal ac current source is applied to the input terminals of an amplifier, and the amplifier output voltage is 2 V rms. Then, a 2-kΩ resistance is placed in parallel with the current source and the amplifier input terminals, and the output voltage is 1.5 V rms. Determine the input resistance of the amplifier.
