Your home electrical system is basically a bunch of wires that bring electricity into your home and take if back out before it has a chance to kill you. This is called a "circuit". The most common home electrical problem is when the circuit is broken by a "circuit breaker"; this causes the electricity to back up in one of the wires until it bursts out of an outlet in the form of sparks, which can damage your carpet. The best way to avoid broken circuits is to change your fuses regularly.

Another common problem is that the lights flicker. This sometimes means that your electrical system is inadequate, but more often it means that your home is possessed by demons, in which case you'll need to get a caulking gun and some caulking. If you're not sure whether your house is possessed, see "The Amityville Horror", a fine documentary film based on an actual book. Or call in a licensed electrician, who is trained to spot the signs of demonic possession, such as blood coming down the stairs, enormous cats on the dinette table, etc.
