# Wien oscillator with amplitude stabilization

Here is Wien oscillator with amplitude stabilization:

I know how this oscillator works in theory, but I'm interested how it would behave in practice. Voltage at Vout node would be sine wave. If we put some load between Vout and ground, it will affect amplitude of Vout, right? Is it because of limited output current of opamp (LM741 in this case)? I simulated this circuit in Multisim. Firstly, I connected 100k resistance on output and I didn't notice any change in amplitude of Vout. Then I used lower values of resistance, and for example, for resistance of 10 Ohms on output, amplitude of Vout is about 0.13V. What are applications of Wien oscillator? Thanks in advance
