Parallel circuits are used in house wiring because all of your appliances are designed to run on 120V AC. If you had series circuits being used, then plugging in more than one device deprives ALL of your devices of the full120V AC. Your higher demanding devices will pull down the voltage. And leave less voltage for the other devices. This will lead to erratic behavior of your devices, if they work at all. I wouldn't suggest having a PC connecting in such a circuit.

Primarily because in a series circuit, when there is an open circuit anywhere on the line, nothing comes on. This is not true in parallel circuits, where there is alway power to other circuit branches should one or more branches open.

Because in parallel circuits everything will work even if one bulb blows because the electrons can take an alternative root and still get the energy they need to light up other bulbs/electrical appliances.

ever had the old christmas light strings that as soon as one bulb burns out the whole string goes dark? that is a series circuit, now imagine you are listening to the radio, doing your home work online, your mom is vaccumning the living room, and dinner is in the microwave. SUDDENLY the kitchen light blows a bulb, and everything else shuts off, get it?

if you had one bulb go out, then the rest of whats on that circuit would be out too.
also voltages would fluctuate throughout the circuit.
hard to find appliances like that
