AI Thread Summary
Using magnets and capacitors in a generator setup cannot create more electricity than the energy input due to the law of conservation of energy. The process involves generating electromotive force (emf) through the relative movement of a conductor in a magnetic field, not by magnets pushing currents directly. Connecting capacitors in series or parallel does not increase the total energy output beyond what is supplied. The energy stored in capacitors is limited to the energy initially provided to the system. Understanding these fundamental principles of electricity and magnetism is essential for accurate applications in energy generation.

Suppose you made a generator by connecting several magnets pushing currents through wires into a capacitor. Now suppose you connected this capacitor to another capacitor by a wire coiled around another wire both connected to the next capacitor. Could this work in creating more electricity for the second capacitor?

I am not perfectly sure what you are asking, but if you ask if there can be more electrical energy or power than before, the answer is no; it is very, very well known that energy can't be created nor destroyed due to the law of conservation of energy.

"A wire coiled around another wire" sounds like a twisted pair cable. It does not create more electricity than is put into it.

Magnets do not "push currents through wires", the relative movement of a conductor and a magnetic field will generate an electromotive force (emf).

Learning the basic principles of electricity and magnetism can be done from books or reputable websites, such as:

The amount of energy generated and stored depends on the physical energy input to the moving magnets (generator). You cannot get more energy out than you put in.
 
I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
