How can push-pull circuits be used?

I understand how a push-pull circuit works, but I don't quite understand how it can be used. In my understanding, a push-pull circuit is able to send current in two directions, depending on its power supply frequency. I have read some materials that…

Is this push pull amplifier wrong?

Under the following tutorial: http://www.allaboutcircuits.com/textbook/semiconductors/chpt-4/biasing-techniques-bjt/ They explain push pull operation. But should't negative terminal be separate with the ground? Dont we need +Vcc and -Vcc Here is the…

Ability to push and pull objects (theory)

So, I do not know much about electricty but it has always been interesting to me. (Especially solar cells) but negative is attracted to postive, etc. So couldn't you theoretically have an "object" in your hand with postive energy and a "object 2"…
