How does the type of circuit affect the brightness of two light bulbs?

This has to do with the potential difference(voltage) reaching each bulb.
If the bulbs are placed in series, the voltage will be divided among them(for example, 9V battery powering two identical bulbs will result in each bulb getting 4.5V). Thus, they would each only be One fourth as bright than if there was a single bulb as the power is Voltage squared. If Voltage is halved then power goes one fourth.
If the bulbs are placed in parallel, the current(amperage) is divided instead, resulting in each bulb getting the same voltage. This will result in both bulbs having brightness equal to a single bulb.

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
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.
In a parallel circuit how is the brightness of the light bulbs?
the bulbs would be very bright seeing as the two or more light bulbs have very easy excusable paths for electricity to flow and get to the light bulbAnswerBecause the voltage across each branch of a parallel circuit is the same, each lamp will be subject to its rated voltage and, therefore, will operate at its rated power output.
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.
How does light bulbs in a circuit affect the current size?
They don't unless you speaking about a parallel circuit in which total currect would be the sum of all the currents in each light bulb (The more light bulbs, the more current draw) If you're talking about a series circuit, nothing at all happens to the current, as in a seires circuit current is constant throughout the entire circuit (voltage changes). In a case such as this the more light bulbs in the circuit, the less the voltage becomes across those bulbs (furthest from the source), thus they will become dimmer due to lower power (P=IE).

Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
How does the amount of magents and wire affect the brightness of a light bulb?
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.

How does area of the circuit affect brightness of bulb?
if light is low it can cuase the bulb brightnees.
Are there supposed to be light bulbs in a parallel circuit?
Yes, light bulbs can be powered by a parallel circuit.

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 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.
Does marijuana grow with energy saving light bulbs?
The amount of energy used by a lightbulb does not affect a plants growth, only the brightness and spectrum of the light produced.
How are light bulbs efficiency increased?
The brightness of a standard bulb is directly proportional to the amount of voltage drop across the bulb itself. Thus, to increase the brightness :-Pass more current across the bulb by reducing the resistance of the circuitIncrease the voltage across the bulb, or the circuit. Change the supply.
