Explanation:
Q8 The answer is that the lights are connected in series but the bulbs have a trick. Let's take a closer look at one of the light bulbs in the strand. A shunt wire (bypass wire) in a Christmas light. ... It would mean that most of the current going through this bulb would run through this wire and not through the filament
Q9 Two light bulbs on the same series circuit share the voltage of the battery: if the battery is 9V, then each bulb gets 4.5 volts. ... Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit.
Q11 In this case, because electricity can flow in more than one path, even if one of the bulb blows out, the other bulb will still have electrons flowing through it and it will continue to glow. ... Connecting bulbs in parallel allows each to shine equally brightly.
Q12 In this case, because electricity can flow in more than one path, even if one of the bulb blows out, the other bulb will still have electrons flowing through it and it will continue to glow. In the same way, if one of the bulb is unscrewed, it would not prevent the other bulb from lighting up.
Answer:
8. series. because all are arranged in a line.
9.parallel. decreasing the number of bulbs in series decreases the power consumption by each bulb.
11.the flow of circuit current still flows.
12.the flow of current still flows.
