So long as you remain with the range of the device (power supply rails less a volt or two), the output of an op-amp will go to what ever value is required to maintain the input stages (bridge) to remain the same. So, the effect on input voltage on output of an op-amp is dependent on the feedback circuit.
The wording are confusing an op-amp is an op-amp a comparator is another animal. an op-amp can be used as square wave generator by overdriving it but the results are not desirable. However a comparator will be a switch on-off at the set level.
III LM324 Non-inverting AC Amplifier Circuit R1 and R2 form a 1/2V+ voltage divider circuit, which biases the op-amp through R3. The circuit input resistance is R3, and the resistance of R4 ranges from several thousand ohms to tens of thousands of ohms.

An op-amp is a device with two inputs, one inverting and one non-inverting. The output goes to whatever value is needed to make the two inputs the same. This means that, typically, the output is connected to a feedback circuit back into the negative input. This is closed loop, negative feedback operation. Due to the high gain of the op-amp, this configuration makes performance, such as gain and bandwidth, easy to predict.
A: One example is the gain of an op amp the gain is strictly related to resistors in a closed loop. The gain will change % wise as the resistor change % wise
An 'ideal' op-amp has infinite input impedance, and real ones that you can buy for anickel come pretty close. That means that the input impedance or "loading effect" ofan op-amp all by itself is nearly zero, and the loading effect of a circuit that youbuild with an op-amp is completely determined by the components you choose toconnect to it. You design the circuit to load the previous stage in any way you want.
When the feedback of the output terminal of an Op-Amp is given to the non-inverting terminal [pin 3 for IC-741] of that Op-Amp , then , that circuit is called non-inverting amplifier using Op-Amp. This circuit is called non-inverting because the output signal of this circuit is in phase with the input signal.
it is used to design filters using op-amp.

Clipping occurs in the voltage waveform when the input voltage, multiplied by the voltage gain of the op-amp circuit, exceeds the op-amp supply voltage as limited by the output network. The supply voltage and output network, limits the maximum voltage that can be achieved at the output. The op-amp behaves normally within its range of maximum voltage output, and then it is clipped when it reaches the maximum voltage of the circuit.

If that's not what you have expected, then your circuit probably has a design flaw. I don't know much about op-amp circuits myself, but in any case, for anybody to know what is wrong with the circuit, he would need to know more details about how you designed the circuit.
A basic, single transistor amplifier differs from an op amp: 1. The op amp has more gain 2. The op amp may have higher input resistance (so it loads the circuit less) 3. The op amp may have a lower output resistance (so it can drive larger currents) 4. The op amp likely has a lower frequency response (due to the high gain, unless you provide some sort of feedback loop) 5. The op amp is ridiculously complex compared to a simple amplifier 6. The op amp will require a positive and negative voltage (may be unnecessary with a single transistor amplifier)

A: An op amp will have the capability to drive a load equivalent to its maximum output if more current is tried to for out the last stage will saturate causing malfunction of the circuit but if not sustained for too long it need not be catastrophic reducing the load can restore the op amp because of its protective design.
