How to place OP-AMP (741) on the bread board?

FIGURE #1 (waveform result)





FIGURE # 2
If we set R2 = 10 k ohm...


If we set R2 = 20 k ohm...
As you can see, when R2 increase, Vo increase.

Based on that, to get Vo/Vi = -10,
the correct answer for R2 is 100k ohm





FIGURE # 3
gate #3 connect to FG, gate #2 connect to resisotr and ground. Note: The correct value for R2 is 100 k ohm

Voltage Divider (use 3 x 10k ohm resistors)



CASE : When Rx = 100 ohm.


CASE : When Rx = 0 ohm (short circuit).


CASE : When Rx = ∞ ohm (open circuit).




I will prepared a midterm review if possible, wish you all the best for the midterm.
