Question about opamp
Hi, I am new to electronics. I would like to ask a few questions about opamp.
1. Does opamp provide constant current or constant voltage?
2. What will happen to the voltage across and current through a resistive load if it is connected to the opamp's output? Will the voltage always stay the same while current is changing?
3. What will happen if the the resistance of the load is approximately equal to the opamp output impedance? if says an opamp has 100ohms O/I, does the load has to be a lot larger to have the max voltage drop across it?
