parallel as shown in figure 61, view A, and schematically represented in
view B.
In a parallel connection, all positive cell electrodes are
connected to one line, and all negative electrodes are connected to the
other.
No more than one cell is connected between the lines at any one
point; so the voltage between the lines is the same as that of one cell, or
1.5 volts. However, each cell may contribute its maximum allowable current
of 1/8 amperes to the line. There are four cells, so the total current is
1/8 x 4 = 1/2 ampere.
In this case, four cells in parallel have enough
capacity to supply a load requiring 1/2 ampere at 1.5 volts.

depicts a battery network supplying power to a load requiring both a voltage
and current greater than one cell can provide. To provide the required 4.5
volts, groups of three 1.5 volt cells are connected in series. To provide
