Batteries

(Basic)
Batteries
connected in a
parallel
circuit.
The
water
current is
stronger and
turns the

faster.
Each one only
needs to
produce half
the energy.
♦ When a single battery is used to power a single miniature bulb:
♦ When one miniature bulb is powered by two batteries in a series circuit:
♦ When a miniature bulb is powered by two batteries in a parallel circuit.
There is a limit to how high
a single pump can
pump water.
Two pumps are stacked up and pump the water twice as
When two pumps are lined up they last longer as they
each provide only half the water needed. The water
doesn't need to be pumped up high so
the voltage remains unchanged.
high, which doubles the current
and increases the force of the
water that hits the water wheel.
The amount of running water
remains the same.
It is
brighter.
The brightness
is the same.
It is the same as if only
one battery is used.
It will stay on for
twice as long.
