I don't really like this question, what do they mean by "power"?
Different power circuits are needed in different types of household appliances because each circuit is designed to manipulate current in such a way that it can achieve a certain purpose.
Example: a transistor needed an npn or a pnp junction for it to function in a way that achieves its purpose by acting like a switch while a light bulb will need a filament that heats up as current passes for light to be emitted.
It is not possible to use an npn junction to emit light under practical condition and nor is it possible for the filament in a light bulb is act as a transistor.
Therefore, different circuits are required depending on the purpose of its application.

Electrical circuits can either be connected in series or parallel.
A parallel circuit is generally used to connect lights because if one fails, it does not affect the entire circuit. Connecting lights in parallel is also preferred over series due to the smaller voltage drop across the components, thus the brightness of the lights will not be greatly affected.
Parallel circuits are also used to connect different appliances as these different appliances draw different amounts of current. A series circuit cannot do this.

Yeah, that makes sense, I thought this was posted in the Ideas to Implementation section so I got confused...lolUmm the OP is in prelim
So its probably the Electrical Energy in the Home topic
