Series of Lights When many lights are connected in series, electricity flows from the power source to the first light, then from light to light until it returns to the power source. When lights are connected in parallel, each light is connected to the power source through its own circuit. The number of ways you can arrange n objects is called "n factorial". 6 factorial is six times more than 3 factorial. There are only three ways to arrange three objects. Therefore, there should be only three lights on your tree.
Using the fact that 6 factorial is more than 3 factorial, we can conclude that connecting six objects in series will result in more lights being on than if they were connected in parallel. This means that connecting your lights in series is better for lighting up your tree.
From the first to the final light, the lights are wired in series. Electric current passes through the circuit from the source to the drain through a single wire. When a voltage is given to the lights, it creates a resistance that allows current to flow to each light bulb. The amount of power that flows is limited by the wiring between the source and drain.
The wiring method used for Christmas light strings is called "series wiring". This means that all the lights are connected in series with each other at both the source and drain ends of the string. This makes it easy to connect or disconnect any number of lights without affecting the power going to the others in the string. The term "series" also means that if one bulb burns out, its impact will be felt by every other bulb in the string.
When you plug in your light string, the source end will have an electric potential while the drain end will have zero volts. Current will immediately begin to flow through the first light in the string to the first resistor (the one that breaks first). As current flows through the second light, the second resistor will heat up until it melts, allowing more current to flow and the third light in the string to turn on. This process continues until all the lights are on, or the source end of the string gets too low in voltage to keep flowing current through the last light in the string.
When many lights are connected in series, electricity flows from the power source to the first light, then from light to light until it returns to the power source. As previously stated, when a circuit is faulty or open, electricity fails to enter through any of the wires, resulting in all of the lights going out. However, if each light were hooked up in a separate circuit, then none of the lights would be harmed by a circuit fault.
The main advantage to connecting string lights in series is that it allows you to use one set of batteries as a backup for the other set. If there is a battery failure in one string, then the remaining strings will still be illuminated. This is not possible with separate circuits because there is no way to link them together in order to form a single backup system.
Also, when stringing lights in series, it is recommended to use a multi-outlet adapter so that each light can be attached to a different part of the cord. This is necessary because it is impossible to identify which outlet a particular wire belongs to when they are inside of a bundle. If you were to try and connect each light individually, then you would need to determine which hole each wire goes into, which would be difficult if not impossible with some lights. By using a multi-outlet adapter, however, all of the wires can be identified by number instead of name, which makes connection much easier.
