Current measurement at resonant frequency (multisim)

[wien]

I managed to make about 110 kHz and about 10 volts using a wien bridge oscillator. However, I need to make a circuit that has 1A running, so there should be a way to check the current, so can you tell me how to do it in this program?

You want to add a load, e.g. a load resistor to you simulation circuit. 1A@10V relates to 10 ohm. Then measure load current.

However it's pretty clear that TL072 (and any other general purpose OP) doesn't source more than 10 or 20 mA. You'll need a power amplifier. There are various suggestions about it in your previous Wien generator threads.
