Definition of Terms
Admittance
The inverse of impedance in units of Siemens. Admittance is a measure of how easily a circuit or
device will allow a current to flow. Resistance is a measure of the opposition of a circuit to the flow
of a DC current, while impedance takes into account not only the resistance, but AC effects (known
as reactance) as well. Likewise, admittance is not only a measure of the ease with which a DC current
can flow (conductance, the inverse of resistance), but also takes in to account the AC effects of
susceptance (the inverse of reactance).
Battery
A collection of jars connected in series. A battery is sometimes referred to as a battery string or
string in this document.
Cell
A collection of plates connected to a single positive and a single negative terminal, immersed in
electrolyte, in a single container. The cell may have multiple positive and negative connections, but
they connect to a single set of plates. A lead acid cell produces approximately 2.1 volts.
Jar
A collection of one or more cells connected in series in a single housing. A 12-volt jar contains six
cells. A jar is commonly and incorrectly referred to as a battery.
String
A collection of one or more batteries.
