a) Why is the external load resistor (RL) of the LM 741 set at 1 k? in Fig. 2? What will happen if RL= 100 ? and Vo= 10 Vp?

b) The LM 741 is connected to a DC source of?12 V. What is the maximum swing (approximately) of Vo before clipping occurs? If RL= 1 k?, what is the maximum power delivered to the load (P=V2p/2RL=V2rms/RL).

c) The gain bandwidth product of a LM 741 op amp is 1 MHz. This means that Gain ? BW= 1MHz or the bandwidth is 1 MHz for a gain of 1. What is the LM 741 op amp bandwidth for again of 20? Can we build a hi-fi audio amplifier with the LM 741 op amp with a gain of 200?

d) Calculate Vo/Vi1,Vi1/Vs1, and Vo/Vs1 for the potentiometer set at Ra= 0 ? and Ra= 100k?.
