AI Thread Summary
A battery maintains a potential difference between its terminals through internal chemical reactions. This potential difference creates a disturbance in the connected circuit, allowing current to flow. The discussion references a comprehensive article on "howstuffworks" for a detailed explanation. Further questions for clarification are welcomed. Understanding these fundamental principles is key to grasping how batteries operate.

Can someone please explain to me, from a physics point of view, how a battery works? Thank you.

Take a look over at the "howstuffworks" website :smile:
 
That's got to be the most practical approach. They have a really comprehensive article that would take us weeks to match with regular posting. If further clarification is needed, feel free to ask here.
Welcome to PF.
 
A battery is a device which performs the function of simply mantaining a potential difference between its two terminals. The potential is created by the reactions that take place within it. Because of this potential that is created there is a disturbance created within the wire which causes a current to flow through the wire.
 
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...
