Let's say we're using an opamp ua741 to function as a comparator.
An ac wave 4 Vpeak, 50Hz is fed into positive input of the opamp. The negative
input is tied to ground. The output of the op amp will be connected to a 10k resistor (R load) and then be shorted to ground
(output->resistor->ground). I expect we'll get a square wave at the output.
Then here's my doubt.
How does the resistance value of output resistor (R load) affect the output voltage waveform??
Thanks.
