Aim:(What is the purpose of this experiment -in just a few words )
to observe what happen when you connect two different circuits ,to make one circuits.
(what do you think will happen ,and why)
We think that the brightness from the light will become dimmer,because there is more electricity being used by the two light bulbs.
(What you will need)
- 3 light bulbs
- 3 circuits
- 3 batteries
Method:(Write in steps. Include variables-what will you change?what will you keep the same?what will you measure?)
Step 1: Set up circuits 1 and 2
Step 2: Turn on circuit 1
Step 3: Turn on circuit 2
Step 4: Observe the brightness of the two different lights
Observations:( what happened-include diagram)
The brightness from the light will become dimmer, cause there is more electricity being used by two light bulbs.
Our group feel that to help with our aim we should have done some research about what type of circuit to create. We think that what circuit we did create effected the end result of the experiment. Afterwards, we did some research on series and parallel circuits to decide that should have done one of those. They look like this:
There are different types of circuits; two circuits that we focused are called “series and parallel”. Components that are connected in series are connected along a single path, so the same current flows through all of the components. Components connected in parallel are connected so the same voltage is applied to each component. In other words, If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel.
We think that after researching about this we should have maybe done something like the parallel circuit.
Our experiment was successful because what we thought would happen did happen. The light bulbs on the larger circuit were dimmer than the light bulbs on the normal circuit. This happened because the electricity running through the larger circuit was being used up faster by the light bulbs than the smaller circuit because there is more wire to get through and more light bulbs to power. Our circuit was a series circuit and our group feel that that effected the result of the experiment and should have set up a parallel circuit to compare them.
