Using these data explain why bulbs #2 and #3 are brighter at V
that at V
Using above data and the measured data of current in table 5 explain:
Why bulbs #1 and #4 are brighter than bulbs #2 and #3 at both V
5V and 10V when all the 4 bulbs are in circuit?
Why bulbs #3 becomes brighter after bulb #2 is removed (all other
bulbs remained in the circuit).
Can the lights at you home be connected as shown in Fig. 4? Why?
Discussions and Conclusions
Electricity runs through homes in parallel circuits because they are much
more practical than a series circuit. If one light goes out, the rest of them can still
remain on which is a very important aspect within a home. You can think of it this
way as well: You do not need your refrigerator; oven, and dishwasher running
constantly the entire time do you? Imagine the electrical bill if that were the case.
This is exactly why electricity in homes is not set up in series. It is very inefficient.
