Question

name the type of combination of resistors used for decorative string of lamps​

Answer 1

Answer:

In the actual string of lights, there are multiple wires in one string, several series of lights are together in parallel. The strings are therefore connected in series as well as in parallel. In other words, holiday lights have both series and parallel connections.That is why in such connections when one series of bulbs become defective , it has no effect on the other strings of bulbs attached to it in parallel. This is the same reason why there are times when only a portion of the lights goes out – because they are in series.

When only one bulb goes out in the series, the entire series turns off. In that case, if you are lucky enough to find the culprit bulb and replace it, the strand will glow again.
