What's+The+Difference+Between+The+Two+Circuits?

Parallel circuits are electric circuits in which the element, branches or components are connected between two points with one of two ends of each component connected to each point. Series circuits are circuits which supply electric power to a number of devices connected end to end so that the current only have one path to follow through the circuit. -WikiAnswers

When a simple series is connected, a single pathway is formed through which current flows. A parallel circuit, forms branches, each of which is a separate path for the flow of electrons. Both series and parallel connection have their own distinctive characteristics. In a series circuit, when one of the bulbs or one of the wires is left open or is broken, the entire circuit ceases. The break opens the circuit. Less expensive Christmas lights are usually of this type, and you have to search for the defective bulb. A parallel circuit is designed so that if one branch is defective, the flow of electricity will not be broken to the other branches. Click here for more information

====__A Student's perspective__ Donald: The difference between a series and parallel cicuit is the power of it. As you know, a series circuit only has 1 wire outlet and has 1 battery source. However, on a parallel circuit there can be more than 1 wire source and batteries. If you remove a wire/ battery from a parallel circuit the light on the light bulb goes weaker than that of a series circuit.====
