What does a parallel circuit do?

Answer 1

A parallel circuit has more than one resistor (anything that uses electricity to do work) and gets its name from having multiple (parallel) paths to move along . Charges can move through any of several paths. If one of the items in the circuit is broken then no charge will move through that path, but other paths will continue to have charges flow through them. Parallel circuits are found in most household electrical wiring. This is done so that lights don't stop working just because you turned your TV off.

Answer 2

A parallel circuit works because both components have their own path from the battery and back to the battery.

P.S. you put 2 "work"s.

Answer

Each branch shares a common voltage, so each load is subject to the same supply voltage, and will operate at its rated power (a load will only operate at its rated power at its rated voltage).

Answer 3

Most practical circuits are parallel circuits. A parallel circuit has two advantages: (1) the voltage appearing across each branch is the same as the supply voltage and, (2) on one branch becomes disconnected, then the other branches continue to work. The reason that (1) is important is because for a load to operate at its rated power, it must be subject to its rated voltage which is (usually) the supply voltage. All homes are connected in parallel, as are the various circuits in (for example) a car.
