Cylindrical lithium batteries connected in parallel and then in series
A battery is defined as an electrical element where chemical reactions produce electrical potential. Each electrochemical reaction has a limit to the electric potential difference it can generate between two electrodes. Battery cells are where electrochemical reactions occur to produce a limited. . The electric potential difference measured between a battery's terminals when no load is connected is called the electromotive force (EMF) or no-load voltage. This is the voltage generated when no currentis flowing through the battery. . The entire resistance encountered by a current as if it flows through a battery from the negative terminal to the positive terminal is known as. . Terminal voltage of battery is the potential difference across its terminals when the current is being drawn from it. Actually when load is. .
