What happens to the brightness of the light bulbs in a series with a heater?

They dim as the total resistance of series of resistances is the sum of the resistances; and current = V/R.

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.
You are building a string of lights using several bulbs how is the brightness of the lights related to whether you connect the bulbs in series or in parallel?
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
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 !)
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
When loads are in series the brightness of the bulbs will?
at like 1minute after each other.
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
If you add an extra bulb to your series circuit what will happen to the brightness of the bulbs?
The bulb is dim.Because,the voltage is drops in series connection so you add more bulbs in series the last bulb got low voltage that reason for the bulb is dim
Why do several 40watt and 220volt lamps not light to full brilliance when in series?
To get full brightness, the rated voltage has to be applied across the bulb. When several bulbs are connected in series, the voltage gets devided among these sevral bulbs and correct rated voltage will not be applied acros each bulb, hence the brightness reduces.
Would the brightness of a parallel circuit of 3 globes increase or decrease when a fourth is added?
The brightness would remain constant but the power draw will increase. If the circuit was series wired, the brightness would go down as you added bulbs.
What happens to the current in the other lights if one light burns out in a series circuit?
It depends what is the outcome of burning. If that light has created open circuit, circuit will break and there will not be any current. But if there is short circuit means overall resistance is decreased. Thus current will increase. Besides overall brightness will also increase. Thus, if in a series lesser the number of bulbs more will be brightness.
Which circuit has brighter bulb side by side?
Bulbs in a parallel circuit draw the same amount of current, so each will display the same brightness. Bulbs in a series circuit share the current so all bulbs will appear dimmer.
