If current passes through a light bulb, it will light. No current - no light. In this activity you will investigate the conditions necessary for current to flow by trying to construct arrangements that light a bulb and studying the arrangements that work, as well as the ones that don't work.
1 battery |
1 piece of wire |
1 bulb |
Using the only equipment shown above:
1. Find at least 4 different arrangements that cause the bulb to light. Draw a clear, well-labeled diagram of each arrangement.
2. Find at least 4 different arrangements that cause the bulb not to light. Draw a clear, well-labeled diagram of each arrangement.
1. What would be a general rule that you could use to decide whether an arrangement of a battery, bulb, and wire will light the bulb or not?
