PURPOSE: To show voltages and currents in series/parallel circuits.

DESCRIPTION: Series and parallel combinations of light bulbs can be connected to the 7.5 volt battery source. Meters indicating current and voltage can be inserted in the circuit as required. the two photographs show the system with one light (top) and two lights (bottom).

SUGGESTIONS: This is a non-lethal version of demonstrations K6-01 and K6-02.

REFERENCES: (PIRA unknown.)

EQUIPMENT: 7.5 volt battery with attached vertical electrodes, three lamps with clip-on leads, lecture meters.

SETUP TIME: 5 min.
