Lab #35.1
Electricity & Magnetism:
Batteries & Bulbs
Purpose
In this activity,
students will explore various
arrangements of batteries and
bulbs, and the effects of those
arrangements on bulb brightness.
Discussion
Many devices
include electronic
circuitry, most of which are
quite complicated. Complex
circuits are made, however,
from simple circuits. In
this activity you will build
one of the simplest yet most
useful circuits ever
invented—that for lighting a
light bulb!
Required Equipment
2 D-cell
batteries, 4 connecting wires, 2
miniature bulbs (1.5-volt or
2.5-volt flashlight bulbs),
2 miniature bulb sockets
