Make a bipolar power supply with two batteries
V(normal) = 9.36
V(with other ground row) = -9.63
DC blocking, current limiting circuit
Adding a resistor and a capacitor on each end allows the AC current to flow while blocking any DC current. If the DC current wasn’t blocked, it could damage expensive equipment such as laptops, speakers, and headphones.

Inverting Amplifier
Work for an inverting amplifier without a potentiometer:
The inverting amplifier changes the output from the op amp (channel 2) to an inversion of the original sine wave (original is channel 1).
