Q1 =>Ideal opamp has infinite output impedance.
FALSE
opamp has zero output impedance and infinite input impedacne ideally. zero impedance means output voltage is independent of output current.
Q2=> A buffer circuit is characterized by infinite gain.
FALSE
a buffer circuit has a unity gain ( or equivalent to zero dB). unity gain means buffer does not amplify the input. whatever will be input it give same ouput.
