参考答案: Batteries are connected in series
to increase the voltage available to a device.
For instance, if there are two 1.5-V batteries in series in a
flashlight, the potential across the bulb will be 3.0 V. The batteries need not be nearly identical.
Batteries
are connected in parallel to increase the total amount of current available to
a device. The batteries need to be
nearly identical. If they are not, the
larger voltage batteries will recharge the smaller voltage batteries.
