Question

3. (TCO 4) The typical open-loop voltage gain of an LM741 op amp _____.           

   is approximately equal to 200,000 at low frequencies
                                        depends upon the circuit closed-loop voltage gain
                                        is infinite
                                        is close to 1 (unity gain) at low frequencies
              

4. (TCO 4) The LM741 op amp typical characteristics include _____.                                                            an input resistance of about 2 M
                                        an output source resistance of about 100
                                        an input offset voltage of about 1 mV
                                        A, B, and C

Explanation / Answer

3rd answer is

Open loop gain is very high as in open loop configuration op amp always amplify the voltage difference in the order of 1 micro volt.so answer is 1st.

And ideally gain is infinite as gain= vo/ vid

4th answer is...

Ri is very high arround 2 M ohm ( op amp is VCVS)

Ro is low I.e 100 ohm

Input offset is low

So all answers are correct
