Question
Decades ago, holiday lights were wired in series, so that if one bulb in a string burned out, all the lights in the string went dark because the burned-out bulb interrupted the circuit. Today's lights are wired at least partially in parallel, so that if one light goes out, many others in the string remain lit.

Decades ago, holiday lights were wired in series, so that if one bulb in a string burned out, all the lights in the string went dark because the burned-out bulb interrupted the circuit. Today's lights are wired at least partially in parallel, so that if one light goes out, many others in the string remain lit. Fig 1 Part A In which circuits in (Figure 1) does one bulb burning out leave all other bulbs lit? Check all that apply. Part B In which does one bulb burning out cause one or more of the other bulbs to go out? Check all that apply.Explanation / Answer
Answer is A and B both. Because this is compleately a parallel connection and not a single bulb is dependent on other i.e each bulb makes their own loop and so there is no relation with any other loop.
