Are your LED Christmas Lights series or parallel connected?

Our LED Christmas lights are parallel connected. If one goes out the rest stay on. Here is a brief explanation of the difference.

In electronics, components of an electronic circuit can be connected in series or in parallel. Components connected in series are connected along a single path, so the same current flows through all of the components. Components connected in parallel are connected so the same voltage is applied to each component.

A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit.

In a series circuit, the current through each of the components is the same, and the voltage across the components is the sum of the voltages across all the components. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through all the components.

As an example, consider a very simple circuit consisting of four light bulbs and one 6 V battery. If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the next bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel. If the four light bulbs are connected in series, the same current flows through all of them, and the voltage drop is 1.5 V across each bulb. If the light bulbs are connected in parallel, the current flowing through the light bulbs combine to form the current flowing in the battery, while the voltage drop is 6 V across each bulb.

In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit kills the circuit. 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.
