PARALLEL CIRCUIT

Background

Light bulbs are in parallel if they are side-by-side. They still share the electrical energy but they affect each other differently than if they were in series.

Materials Needed

2 batteries in holders
1 breadboard
2 light bulbs
4 wires with washers
push pins

Procedure

1. Connect up the simple circuit with 2 batteries.

2. Now replace the single light bulb by two in parallel as shown.

3. Remove one bulb from its socket. What happens? Why?
