Is it better to wire a house using a series circuit or a parallel circuit?
A a series circuit because if one circuit is broken, then the other circuits will still work
B a series circuit because if one circuit is broken, then the other circuits will not work
C a parallel circuit because if one circuit is broken, then the other circuits will still work
D a parallel circuit because if one circuit is broken, then the other circuits will not work

C a parallel circuit because if one circuit is broken, then the other circuits will still work

Explanation:

Electrical devices can be connected in two different configurations:

- Series configuration: in this configuration, all the devices are connected along the same branch of the circuit. This way, the current flowing through the devices is the same for all the devices. Also, the total resistance of the circuit is equal to the sum of the individual resistances:

- Parallel configuration: in this configuration, the devices are connected in different branches of the circuit. This way, the current flowing through them is different, however they have same potential difference across them. In this case, the total resistance of the circuit is given by

The main advantage of the parallel configuration compared to the series configuration is that in a parallel circuit, if one component is turned off/broken, the other components will continue working, since they are connected on separate branches. Instead, in a series circuit, when one component is turned off/broken, al the others also stop working, since they are along the same branch.

So the correct answer is

C a parallel circuit because if one circuit is broken, then the other circuits will still work

b would be the answer
