How do you change the brightness of the bulb?
Increase the voltage supply.
What is the increase in brightness of light is called what?
It gets brighter (at least until it burns out)
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 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.
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.
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 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.
Why does the brightness of the bulb increase when you add salt?
This phenomenon doesn't exist or you think to a flame test.
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 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
Does a light bulb have vacuum in it?
Yes, the inside of a light bulb is vaccum sealed to increase the lifespan and brightness of the bulb. If there was air in there, the filiment would burn up and not last very long. This was an important discovery made by Thomas Edison when he invented the light bulb.
What does the Hertzsprung diagram show about the main sequence?
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature
