Did You Know?
In a parallel circuit, two sets of wires run side by side off a common power supply (i.e., battery). This way, lights installed on one circuit will not interfere with lights connected on another. It also means that all the lights receive the same amount of voltage from the battery because they are all equally connected to it - every bulb has one wire going to the positive terminal and another wire going to the negative terminal. That's why most holiday lights today are wired in parallel circuits. |

| Complete the following: |
| 1. |
(a) |
What happened to the first bulb's light when you added a second bulb to the circuit? |
| |
|
|
| |
(b) |
What happened to the first and second bulb's lights when you added a third bulb to the circuit? |
| |
|
|
| |
(c) |
What happened to the first, second and third bulb's lights when you added a fourth bulb to the circuit? |
| |
|
|
| |
(d) |
What happened to the first, second, third and fourth bulb's lights when you added a fifth bulb to the circuit? |
|
|
|
| 2. |
(a) |
What happened to the first bulb when you unscrewed the second bulb? |
| |
|
|
| |
(b) |
What happened to the two other bulbs when one was unscrewed? |
| |
|
|
| |
(c) |
What happened to the three other bulbs when one was unscrewed? |
| |
|
|
| |
(d) |
What happened to the four other bulbs when one was unscrewed? |
| |
|
|
| |
(e) |
Why do you think this happened to the light bulbs? Explain. |

This circuit diagram shows two lights and a cell connected in a parallel circuit (Note: battery is two or more cells connected together). Using your Circuit Symbols sheet, draw a parallel circuit with five lights and one cell on the back of this sheet. |
