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

FIGURE #1 (waveform result)

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

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

4a Result

4b Result

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.
