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 if three 60 W light bulbs are mistakenly wired in series and connected to a 120 V power supply Assume the light bulbs are rated for single connection to 120 V?
Since the bulbs are in series, each one will have 40 volts across it instead of the 120 volts it was designed for. The bulbs will glow very dimly or not at all.
If you have three light bulbs two are connected in parallel This combination is connected in series with the third bulb What is the relative intensity of each bulb?
All the bulbs should be the same brightness because they are all receiving the same voltage, which would be half the voltage of the original source. To visualize why this is the case, imagine the electrons moving through the circuit. The electrons can take two paths through the circuit but either way they have to pass through two light bulbs. The two bulbs in parallel may, however, appear slightly dimmer because the current is split between them and restricted by the third bulb. Assume that the resistance of all light bulbs are equal. The current through the light bulbs in parallel will be 1/2 that through the one in series as it is split equally between the two of them. The intensity of each light bulb is proportional to the power through each bulb. Power is I2R. So, if the total current is 1 amp the power through the series light bulb is R, where the power through the parallel light bulbs will be 1/4R. Therefore the intensity of the parallel bulbs will be 1/4 the light bulb in series.
If two light-bulbs are connected in a series circuit and one of the light-bulb's current flowing is 0.5 A what is the current flowing in the other light-bulb?
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
What would happen if one of a set of light bulbs burn out in a parallel circuit?
It depends on the circuit. If it is a constant-current circuit, any light bulbs connected in parallel with it will become brighter. If it is a constant-voltage circuit like a typical household circuit, nothing will happen. Any connected in series with it will go out.
Two light bulbs of resistance R1 and R2 R2R1 are connected in series Which is brighter?
The brightness of a light bulb is related to its power. In all electrical circuits, power is equal to Voltage*Current. Since the two bulbs are connected in series, they must have equal current. The voltage across any given element in a series circuit is proportional to its resistance, so whichever bulb has the higher resistance has a higher voltage and thus higher power and is brighter.
What type of circuit is it called when light bulbs one after another are connected?
In series
When two light bulbs are connected in series the?
When two light bulbs are connected in series , there is voltage drop which causes the second lamp to dimAnswerWhen two lamps are connected in series, neither lamp will be subject to its rated voltage and, so, each lamp will be dim. Surprisingly, perhaps, the lamp with the higher power will be dimmer than the lamp with the lower power!
Why does an incandescent light bulb grow dimmer with use?
Over time, the heat produced causes the filament to grow thinner. This causes the light bulb to grow dim.
Why do two incandescent light bulbs glow with different intensities when connected in the same circuit?
When you are wiring two light bulbs in SERIES, you split the voltage to each light bulb in HALF, meaning that it will only glow half the brightness per bulb, but it will only draw the current of one bulb, meaning if the bulbs were connected to a battery, it would last longer to connect them together in series, rather than parallel.

Light bulb in parallel circuit brightness?
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
Will connecting more light bulbs in series make the bulbs dimmer?
yes
When several light bulbs are connected in a series circuit what will happen if on bulb burns out?
Hmm. well, it's a series circuit, so I would think they would potentially follow after the one that went out, right?? Yeah, for sure!
Is it true that if two light bulbs are connected in a series circuit and turning off one will not effect the other?
No, If they are in parallel, turning off one won't effect the other.

What happens if a Christmas light connected in series burns out?
If they are connected in series if one light burns out, the whole string turns off.
