They are parallel, or at least you HOPE they are parallel.
series
they are manufactured in a pattern
Yes you would use a serial circuit You would use parallel circuit lights for a Christmas tree because if you used series circuit lights, and one of the bulb blows, the rest of the bulbs will go out. But with parallel circuit lights, if one bulb blows the rest of the bulbs will remain their brightness.
parallel circuits can be used for lots of things.Things such as : . Christmas tree lights False for A+
Generally in a parallel circuit
Cheap Christmas tree lights.
Always parallel. Homes should never be wired in series. (That would be like the old Christmas tree lights where, if one bulb burned out, the entire string would not light up.)
Christmas tree lights, this parallel circuit prevents one bulb failure from turning off the whole string of lights.
Christmas tree lights and computer cables are also connected in series.
Christmas tree lights and computer cables are also connected in series.
they can be both, all depends where you get them
Series means that the same current passes through every component, so in Xmas lights, if there is one dead bulb or a break in the circuit, every light goes out. If Xmas lights were in parallel, they would each have a direct connection to the power supply, and would all be independent of each other.
when lights are wired in series same amount of current flows through each light through out wire so the intensity of lights dont decrease and all lights glow with same intensity
