BATTERY OPERATIONS
Once the basic theory behind the operation of batteries is understood, we can
apply these concepts to better understand the way batteries are utilized.
EO 1.6
DESCRIBE the relationship between total battery
voltage and cell voltage for a series-connected
battery.
EO 1.7
STATE the advantage of connecting a battery in
parallel
with
respect
to
current-carrying
capability.
EO 1.8
STATE the difference between primary and
secondary cells with respect to recharge
capability.
Series Cells
Figure 7 Cells Connected in Series
When several cells are connected
in series (Figure 7), the total
voltage output of the battery is
equal to the sum of the individual
cell voltages. In the example of
the battery in Figure 7, the four
1.5V cells provide a total of
6 volts. When we connect cells in
series, the positive terminal of one
cell is connected to the negative
terminal of the next cell.
The
current flow through a battery
connected in series is the same as
for one cell.
