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
