can you please answer the following !
Thank you
Why do most flashlights have batteries connected in series. Why are the individual cells in a car battery connected in series? What are the essential features in the construction of a flashlight? Make a sketch of the circuit. What does the term "complete circuit" mean? Wires for a speaker in another part of the house do not work. How could you check to see if the wires are broken someplace in the walls? What happens when a light bulb bums out? What happens to a simple flashlight circuit when you unscrew the bulb from its socket? What if two flashlight bulbs were wired in series and one bulb was removed? What if two bulbs were wired in parallel and one was removed?Explanation / Answer
As we know that
The power that both arrangements provide is the same. Either the voltage is doubled (for series) or the current capacity is doubled (for parallel). And power is voltage times current.
The reason most flashlights are in series is simply that it makes for an easier-to-handle tube with one behind the other. There is also a small advantage in having the higher voltage in terms of overcoming minor layers of oxidation at the contacts. Because of that preference for the series arrangement, most bulbs made for flashlights have long been made for 3 volts - for the series arrangement.
