If there are three bulbs in a curcuit will they all glow the same brightness or will one be brighter than other?
With the naked eye they will all come on at the same time. Think of Christmas tree lights do they all come on together. It probably could be measured with an oscilloscope but I don't know.
They will all come on at the same time.
Think of the electrons in the wire as a very tight chain connected to your car while you are being towed. When the chain moves, every link in the chain moves and the car moves as well. Therefore when one electron (link in the chain) moves in the wire, they all move. Meaning every light will come on at the same time.
There are exceptions to this rule, but it would take too long to explain.

What affects the brightness of stars?
The brightness of a star is primarily determined by its size, temperature, and distance from Earth. Larger, hotter stars tend to appear brighter, while stars that are closer to us also appear brighter due to their proximity. Other factors such as the star's age and its stage in the stellar lifecycle can also influence its brightness.
What are the factor that effects the brightness of a star?
Luminosity, size and distance. If all distances were equal, larger and hotter stars would be the brightest. But a so-so star 40 light years away, will frequently be brighter than a brilliant star 40,000 light years away, etc.
How can a star appear to become brighter and dimmer on a regular basis?
A star can appear to become brighter and dimmer on a regular basis if it is a variable star. Variable stars can pulsate, eclipse with another star, or vary in brightness due to other factors. By observing these fluctuations in brightness over time, astronomers can gain insights into the star's properties and behavior.
Why do some stars seem so brighter in the night sky than other stars?
The brightness of a star depends on its intrinsic luminosity, distance from Earth, and atmospheric conditions. Stars appear brighter if they have high luminosity, are closer to Earth, or if they are visible in a clear, dark sky away from light pollution.
Why is the sun brighter than all other stars?
The sun appears brighter than other stars because it is much closer to Earth, allowing us to receive a higher amount of its light and energy. Additionally, the sun is a relatively average-sized star, so its brightness is more prominent compared to much larger or smaller stars.
Is it true that when a round bulb and a long are connected in a parallel circuit the long bulb is brighter than the round bulb?
In a parallel circuit, the brightness of the bulbs connected depends on their resistance and current flow, not their physical shape or size. The bulbs will have the same voltage across them, so if the long bulb has a lower resistance, it could be brighter but this depends on the specific characteristics of the bulbs.
What happens to the brightness of the lights when you decrease the number of light bulbs in a circuit?
The brightness of the lights may or may not change depending on the circuit in which they are wired. In a series circuit, all the bulbs (called lamps) will experience the same current flow. The same amount of current will be flowing through each one, and each one will be dropping some amount of voltage. If we remove some of the lamps and reconnect the circuit, the lamps will glow brighter because there is less total resistance in the circuit. The remaining lamps will end up dropping more voltage, and will glow brighter. In a parallel circuit, removing bulbs (or adding them) will not affect the operation of the other lamps in the circuit (providing the voltage source is adequate). We know that each of the lights in a household circuit is wired in parallel, and turning one or more on or off won't affect the operation (the brightness) of any other light that is on.
When loads are in series the brightness of the bulbs will?
at like 1minute after each other.
What do you notic about the brightness of the bulbs in the parallel circuit as you added more bulbs to it?
In a parallel circuit, as more bulbs are added, the overall brightness of the bulbs remains constant. This is because each bulb gets the full voltage of the circuit and operates independently of the other bulbs. The individual brightness of each bulb may decrease slightly due to the increased current draw, but the overall brightness of the circuit remains fairly consistent.
Is the sun brighter in the winter compared to other seasons?
No, the sun is not brighter in the winter compared to other seasons. The brightness of the sun remains relatively consistent throughout the year.
Do higher wattage bulbs give a brighter light?
Yes, in general, higher wattage bulbs produce more light than lower wattage bulbs. However, the brightness of the light also depends on other factors such as the type of bulb (incandescent, LED, etc.) and the design of the fixture.
What causes one headlight to be brighter than the other?
it is possible that you have two different rated bulbs, check to see if they are the same bulbs. it may be that one of the bulbs is incorrectly fitted which would give a different beam pattern and brightness. check the earth for the two bulbs, if one is poor and gives a high resistance it will affect the brightness, or it may be that the dull bulb has come to the end of its useful life and requires replacement. hope this helps, robb Different intensity bulb or poor ground.
Do two light bulbs in a series circuit have the same brightness?
yes but they will each be less bright then if there was only one light bulb in the circuitAnswerIt depends on their power ratings. If they are different, then the lamp with the lower power rating will be the brighter. The reason for this is that lower power lamps have a greater resistance than higher power lamps and, so, a greater voltage drop appears across the lower power lamp, making them brighter.
What affects the brightness of stars?
The brightness of a star is primarily determined by its size, temperature, and distance from Earth. Larger, hotter stars tend to appear brighter, while stars that are closer to us also appear brighter due to their proximity. Other factors such as the star's age and its stage in the stellar lifecycle can also influence its brightness.
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 is the factor that affects the brightness of the bulb?
The factor that primarily affects the brightness of a bulb is the amount of electrical current flowing through it. The brightness of a bulb is directly proportional to the current passing through it, as described by Ohm's Law (V=IR), where V is voltage, I is current, and R is resistance. Therefore, increasing the current flowing through the bulb will result in a brighter light output.
How fast does light bulb heat up?
Incandescent light bulbs typically heat up to full brightness within a few seconds of being turned on. LED light bulbs, on the other hand, reach full brightness instantly upon being switched on.
