Lab #35.3
Electric Circuits: Be The
Battery
Purpose
In this activity,
students will provide energy to
an electric circuit using their
own muscle power.
Discussion
Batteries
last longer in some circuits
than they do in others. They
last longer when they don’t
have to “work” so hard. In
this activity, you will do
the work of the battery.
That is, you will power a
circuit using the hand-held
generator. You will learn
which circuits are easier to
power and which circuits are
harder to power. And you’ll
gain a better appreciation
for what batteries and the
local power utility do for
you all the time!
Required Equipment
Hand-held
generator (Genecon® or
equivalent), 3 miniature bulbs
(6-volt flashlight bulbs), 3
miniature bulb sockets, 6
connecting wires
