Capacitors Lab Report Conclusion

Capacitors are two conducting plates separated by an insulating material. So when a voltage is applied across the plates, the battery works on the plate to separate the negative and positive charges on the capacitor. In lab 21 we will observe this type of charge in snap circuits by using the snap circuit kit from our lab and a stopwatch. In part two of this lab, I observed how the relationship how current, voltage and resistance are used to through a system in regards to Ohm’s Law.


In lab experiment 1 we will compare difference of the capacitors of the snap circuits in series and parallel charges. The circuits will have the capacitors placed at different locations depending on the type and we will observe the amount of time it take the LED light to turn off. In experiment two we observed the truth of Ohm’s Law V=IR. We will measure different charges of battery

Gather the material needed for this experiment, 470 uf, 1 LED, 1 K Ohm resistor, switch, one 4-snap conductor, or two 3 snap conductors, three 2 snap conductors, one snap conductor and a battery holder. Connect it just like it is done in figure in the Lab manual.
2. Put two AA batteries in the battery holder.
3. Turn on the switch for about two second and flip it back of observing any changes to the LED light. Record the time it takes the light to completely turn off in 1 column in Table 1.
4. Repeat steps 2-3 nine more times and record any observations of time change.
5. Now, in the average time section in Table 1, record the calculated average time.
6. Now remove the 3 snap conductors, places an S there and substitute the 100 uf capacitors. Repeat steps 2-5 with the new circuit and record the new time values under Capacitance 2 column in Table 1. Part 2:

7. Now using the same material from the lab kit, create another circuit using the same materials but starting with the 100uf
