What would be the disadvantage of connecting a large number of light bulbs in series?

Well, like anything in series it's subject to the chain weakness, so if any of them fail the whole string fails. Depending on what kind of lights you're talking, f you get too many in it, the resistance will be too high to actually light at a given voltage. Lightbulbs in series ware exactly what a set of Christmas lights are (before they went LED).

How would you compare the brightness of the bulbs as you increase the number of bulbs?
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
Why are two bulbs in a series dim?

What happens to the current if the number of bulbs stays the same but you use more cells?
If you add more cells in series with the bulbs, the current will increase as the voltage across the bulbs increases. If you add more cells in parallel with the bulbs, the current will stay the same because the voltage of the cells does not increase when they are added in parallel.
If two bulbs in a series circuit are equally bright then they transfer energy at different rates?
Whether or not they're in series is an irrelevant detail. If the two bulbs are equally bright, it means that they're dissipating energy at the same rate. They can dissipate energy at the same or at different rates whether they're in series or parallel circuits. It only depends on the characteristics of the bulbs.
Compare the current in a 2 light bulbs wired in a series circuit?
Since the SAME electrons have to go through both light bulbs, the current in both light bulbs will be the same (Kirchhoff's current law).
Will connecting more light bulbs in series make the bulbs dimmer?
yes
How is the current affected by the number of bulbs?
As the number of bulbs in a series circuit increases, the current decreases. As the number of bulbs in a parallel circuit increases, the current increases.
What do you think will determine the number of bulbs you can light up in a series circuit?
Assuming the bulbs are identical, the voltage drop across each one is inversely proportional to the number of bulbs. So, for example, 240V could power 20 12V bulbs in series. In addition, the circuit would have to be able to supply the necessary current.
Will connecting bulbs in parallel make the bulbs brighter or dimmer?
Neither. Connecting lamps in parallel subjects each lamp to its rated voltage, so they will each operate at their rated power (therefore brightness).

What two circuits one series and one parallel use light bulbs to provide resistance. Both circuits have the same number of light bulbs?
Series circuit gives higher resistance compared to parallel circuit.
What are the uses of series connection?
Disadvantage of series connection: 1.If one point breaks in the series circuit, the total circuit will break. 2.suppose if you want to connect 3 bulbs rated 230v,5A in series then due to added up resistance less current flows and the bubs are dimmer
Is it sensible for the TV to be connected in series with the light bulbs?
Connecting light bulb is equivalent to connecting a resistance. If you have connected light bulb, there will be some voltage drop across it and your TV may not get sufficient voltage. However if resistance is not big enough, than it wont have any effect.

What happens to the brightness of the other two when one of the bulbs burn out three identical bulbs are wired in series?
As a series circuit, as asked, all bulbs will go off because of that just one bulb.
What happens to the current if the number of bulbs stays the same but you use more cells?
If you add more cells in series with the bulbs, the current will increase as the voltage across the bulbs increases. If you add more cells in parallel with the bulbs, the current will stay the same because the voltage of the cells does not increase when they are added in parallel.
What will happen if you connect identical integrated circuits in series?
Connecting integrated circuits is not the same as the much simpler cases of resistors, capacitors, inductors, motors, light bulbs, etc. Integrated circuits have designated functions, and they operate in concert with the surrounding circuit design. As such, the idea of "connecting identical integrated circuits in series" has no meaning in the general case. You would need to state what kind of integrated circuit is involved.
