A Parallel Circuit
A parallel circuit is a circuit where the components are connected parallel to each other. So the current will flow in several paths, but the voltage across each of the components is the same, and the total current is the sum of the currents through each component. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and the last one will still function. Another example also can be found in your house, that is the television which can be turned off without turning off the lights. If a device is added to or removed from the circuit, the other devices still have the same voltage as before. The total current equals the sum of the currents in the branches. Parallel circuits are used in homes because they permit the current to flow through many paths even when it cannot flow through one path.
