## Parallel Circuit Wiring

Wiring electrical elements in parallel means that each will have its own distinct loop. Therefore, there are multiple paths through which current can flow.

## Series Circuit Wiring

A circuit that is wired completely in series is just a single loop, which means that there is only one path through which current can flow. The current across each element is therefore the same because it never gets split across two different paths. In this circuit diagram, two resistors are wired in series:

## Circuits

An electric circuit is simply a connection of electrical elements. A light bulb connected to a battery is a basic circuit. The battery delivers voltage to the system, and the light bulb introduces resistance.

## Power

The standard unit for measuring electrical power is the Watt, which is equal to 1 Joule/second. In the context of electricity, power is often used to describe either an electrical device or a generation system. In the first case, the power rating of a device gives its instantaneous electrical demand. For instance, in order to remain lit, a 10-Watt compact fluorescent light bulb would continuously require 10 Watts of electrical power.

## The Fundamentals of Electricity

Electric charge (conventionally denoted Q) is a property of matter that describes the force experienced (and exerted) in the presence of other electrically charged matter.
