What is the factor that affects the brightness of the bulb?
number and voltage of the cells in the circuit resistance of each bulb
What differene will different length or thichnesses of wire have on the brightness of a bulb?
Tungsten. Thicker = less resistance = dimmer.
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
Is a bulb dimmer when the wire is longer?
The resistance of a wire is proportional to its length so increasing the length would increase the resistance of the wire. The higher the resistance of a wire the lower the voltage will be across the bulb so theoretically, the bulb will be somewhat dimmer.However, the resistance of a wire is extremely low compared to that of the light bulb. Electrical wiring is designed and installed so that the wire resistance is insignificant compared to the resistance of the load, such as the bulb. In a well planned wiring system, it will be impossible to see any difference in brightness in bulbs regardless of their location in the electrical circuit. In most cases, it will require very sensitive measuring equipment to detect any difference at all.
Does the size of the light bulb affect how much energy it uses with wire and a battery?
No, only the resistance of the filament counts (normally marked as "wattage" on the bulb).
What is the factor that affects the brightness of the bulb?
number and voltage of the cells in the circuit resistance of each bulb
Does adding more wires affect the brightness of the bulb?
NO
What would happen to the brightness of the bulb if you added a second bulb in with the first?
The brightness of a bulb would not change if you added a second bulb in parallel with the first.Unless, of course, the increased current exceeded the power supply's capacity causing a reduction in voltage.
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 do you increase the brightness of a blub in a simple circuit?
Brightness can increased by increasing current flowing through the bulb, but current can be increased only indirectly, by 1. Increasing the Voltage across the bulb 2. Reducing the Resistance of the bulb. Brightness is proportional to Heat energy used/produced, which is = I*I*R*T I= Current R=Resistance T= Time
How does area of the circuit affect brightness of bulb?
if light is low it can cuase the bulb brightnees.
How are light bulbs measured?
Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.
What differene will different length or thichnesses of wire have on the brightness of a bulb?
Tungsten. Thicker = less resistance = dimmer.
How does a change in the size of a current affect the light output of a bulb?
The bulb has resistance which then gets smal
How do you alter the brightness of a bulb?
You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
Can different wires affect the brightness of a potato powered light bulb?
yes it can be powered by a potato:)
Does anything happen to the brightness of the bulb when you add an extra battery to a simple circuit?
We did this experiment in class, the more batteries added, the brighter the bulb will become!
