#### exists and is an alternate of .

The factors which affects the brightness of the bulb are:

1. Changing the number of batteries
2.Number of bulbs
3.voltage
4.The length of wire
5.Is the bulb in series or in a parallel circuit
6.Is the bulb in a complete circuit or it is broken
_________________________

There is only one factor that affects the brightness of a particular lamp. For a lamp to operate at its rated power, it must be supplied at its rated voltage. So, voltage is the one and only factor.

------------------------

To elaborate a little on the above:

There are many choices of independent variables. For example, if we know the material of the filament, the applied voltage and the current flowing through the filament we can compute the power output in the visible spectrum (i.e. the brightness). If we don't know either the current or the voltage (but know at least one of those), we can still get by provided we know the resistance of the filament at the relevant temperature. In turn, the resistance of the filament can be computed if we know its cross-sectional area and length (since we know the material and therefore the resistivity as a function of temperature). There are many possible choices, as you can imagine.

# How do you measure the brightness of a light bulb?

In Lumens, not Watts. Lumens is a measure of the perceived power of light.

# What determines how bright a light bulb is?

Generally speaking, it is the amount of applied voltage that determines how brightly any light bulb (called a lamp) glow. This idea applies to the common incandescent lamp.

# Who invented the first Bright Effects Light Bulb?

Answer : . "The First Bright Effects Light Bulb was invented in 2007 by Robin Woolum when Robin Woolum bought Bright Effects Light Bulbs at Lowe's!!!!!!"

# What is the bright effects light bulb website?

I have found after a fair amount of time searching, that these are primarily offered through Lowe's. The product is made by FEIT Electric: Ă˘Â€Â˘ E-MAIL info@feit.com

# What determines the brightness of a light bulb?

Usually the wattage determines this

# What effect would a pencil have on the brightness of a bulb?

A pencil has nothing to do with the brightness of a light bulb.

# Is the brightness of a light bulb determined by its filaments?

Though there is a bit more to the story than this, yes, it is generally true that the brightness of a light bulb, sometimes called a lamp, is a function of its filaments. For

# How is the brightness of a light bulb determined?

Brightness of a light bulb depends on the power, current,resistance and size of the filament. Lumens is the unit ofmeasurement for the brightness of a bulb. A bulb has morebri

# How does length of wire effect brightness of bulb?

Wire has a certain amount of resistance. As electricity flows down the wire, some of the voltage is lost in the wire before reaching the lamp. So, the longer the wire, the les

# 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.

# Why do light bulbs take long to get bright?

You're probably thinking of the kind of bulbs used in floodlights (streetlights or industrial lighting) which do not shed much light when they're first turned on, because they
