I'm new to the 741 op-amp, and I'm trying to understand some basic concepts, like what will happen if the load resistance is low and approaches the output resistance of the 741 op-amp? (The output is feedback into the negative terminal with the positive terminal grounded creating an inverted output.)
My though is the low resistance will increase the current that is feed back into the negative terminal, but i don't how that will effect the 741 op-amp. Also with the low resistance and high current the input voltage will be greater at the input, and in fact decrease the gain of the op-amp, and the output voltage will be low. Does anything else happen or am I way off on everything???
Thank you everyone
